Ok My current Static is: Local 172.17.250.253 Subnet 255.255.0.0 Gateway 172.17.0.1 Dns1 192.168.20.6 Dns2 67.17.215.132 If i set it up as static I can't ping the gateway, DHCP works fine. So I have been running it as DHCP till I have a bit more time. The only Difference Static and DHCP is the last two Octets of the local address. I tried to set up the Static address again this after noon, it worked I pinged the gateway twice, went out the browser and nothing, went back and tried to ping again, can't reach address. Reset DHCP, it works fine So I tried to set the static up to the DHCP address. I can ping the gateway, but can't ping either DNS servers? I'm back to running DHCP.

Hello Hami, It appears that you abandoned your original posting and that this is a duplicate one: http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/662e03ae-bca0-4059-99f0-c9930b4dac03/ So I assume that you have validated that it is not a network driver issue. In the original posting you mentioned that the router was actually a server. Have you checked that your routing table on that server/router is correct. An incorrect routing table could affect the ability for the packets to return back to the client. You may want to install a packet capture application both on this computer and the server to see where the packets are actually going (Wireshark is a good application and its free). However, I would first validate that the server (router's) routing table is correct. While I understand that it works for IPs in the DHCP range, it does not work for the IPs in the static range. You can check to see if this is a symptom by just assigning (temporarily) an IP from the DHCP range, statically on the server. If the problem persists, then it would not be a routing issue on the router (an IP is an IP regardless if its DHCP or statically assigned). If the DHCP IP assigned statically still causes an issue, I would definately look at the router and/or run some packet captures. Visit: anITKB.com, an IT Knowledge Base.

Yeh, I thunk, it might get a better response in a forum with the Network in the description? I updated all the network drivers (one set were Marvel, and the other were Realtek), and it not working. Yes the router is a server, its a third party app. All of the testing is with the app shut down. I did try to use a DHCP address, I set it up as DHCP, got a address, reset the address to static (using the DHCP address), and the symptoms changed. With the true static address, I could not reach the Gateway, with the DHCP static address I could reach the Gateway but could not reach the DNS. In the last line you refer to the router, your referring to the ISP router, I keep my router app offline during the testing. I'm going to D/L the capture app and take a looksee. Back soon Hami

Ok, new info! When it works the traffic goes out the first Nic. And when it fails it goes out Nic 2. the firs nics gateway is 172.17.0.1, this is the address I'm pinging. If i disable the second Nic, it goes nowhere! and fails! Any ideas on a fix? Hami

first, second NIC? If you can provide a simple diagram that would be helpful. Visit: anITKB.com, an IT Knowledge Base.

It is really simple, a 2008 box with two Nic's. Nic one is connected to the outside world, it can either pull a DHCP address, or a static address. Local 172.17.250.253 if it is DHCP 172.17.xxx.xxx, the rest stays the same. Subnet 255.255.0.0 Gateway 172.17.0.1 and two DNS's Nic two is connected to the private Internal network. Local 192.168.xxx.xxx Subnet 255.255.255.0 Gateway 192.168.xxx.1 The router app is offline. if i set it up on DHCP it works fine and I can ping the gateway and get to the internet If I set to a static IP, I get one maybe two sets of Pings to the gateway, and then it is unreachable. watching the traffic I can see the first sets of pings go out and come back fine. after it fails, if I go to the Nic 2 and watch the traffic, I see the ping go out, but no return. Hope this helps Hami

You can only have one gateway per machine, not one per NIC. If your "public" NIC gets a gateway from DHCP, the "private" NIC gateway setting should be blank. Bill

A few gapes being filled in my knowledge base. OK removed second gateway address, no change, it's gotta be something something simple/stupid? Hami

Hi Hami, Could you post the route table and ipconfig /all result here for further investigation ? Are there any server or scope options set on DHCP server ? I suspect this may a routing issue. Like Bill mentioned only one default gateway should be configured on any multihomed computer. Default Gateway Configuration for Multihomed Computers http://support.microsoft.com/kb/157025 Thanks.

Hello Hami, This is definately likely to be a routing issue. While reviewing the information above, it seems that you have other components on your network that you have not described as of yet. For instance, you have addresses referred above to 192.168.20.x and 192.168.69.x. It would really help if you would provide a high level network design. Its not clear on how your network is designed based on the configuration and routing table listed above. Also, there is no need to mask ('x' out) any of your internal IP addresses. Having your internal IP scheme doesnt really increase any security risks since we do not know your public IP address. It makes it harder to understand your layout. However, post whatever is within your comfort level. Visit: anITKB.com, an IT Knowledge Base.

Ok 192.168.20.xxx is on the public side (my ISP) it is the DNS server 192.168.20.6 and the DHCP server 192.168.20.12, info in IPCONFIG 192.168.69.xxx is my private side and currently the address are cleared and the Nic is disabled. Info listed in earlier text the blanked out was not a IP address it was a URL of my ISP, the rest of the xxx are a variable address or should have been listed a 0 showing a network. at this point it is not even a network, it is a 2008 server trying to connect to the internet with Via a static address. I have taken out all/any things that could make things complex/confusing, start with the simple, get it to work, add till it fail, fix it add more complexity. I'm not hiding anything, there is no high level of design, it is a box tiring to connect to the internet. Hami

Hello Hami, So is it safe to assume that your network design looks like this (http://i56.tinypic.com/2ywv5nc.png)? Are the IPs 192.168.20.6 and 192.168.20.12 other servers in the yellow zone pictured above or one on the server/router and the other IP the ISP Modem/Router? So with this design and the config listed above, you should be able ping 172.17.0.1 from 172.17.20.253 regardless whether the IP config is static (172.17.20.253/16) or dynamic (172.17.12.214/16)on the server. If you are still unable to ping the gateway from the server these are the things you have to verify: 1) on the server, the gateway's (172.17.0.1) MAC address must be listed in the arp cache (arp -a) 2) On the server/router, the 172.17.0.1 NIC interface should not have a default gateway listed. ONly the 192.168.20.x interface should have a gateway listed. 3) Review the server/router's Routing table. There should be a clear indication that to get to the 172.17.x.x network, the packet must leave through the 172.17.0.1 interface. 4) Review the server's routing table. There should be a clear indication that to get to the 172.17.x.x network, the packet must leave through the 172.17.20.253 or 172.17.12.214 interface depnding on the IP you have configured. Make sure that your Network Driver on the server is correct and up to date. Do the same for the server/router. Visit: anITKB.com, an IT Knowledge Base.

I will go thru and check all that you ask. Maybe I don't understand, but let me explain how this is put together. Server 1 (the only one) Nic DHCP Static status 1 Local 172.17.xxx.xxx 172.17.250.253 Enabled Subnet 255.255.0.0 255.255.0.0 Gateway 172.17.0.1 172.17.0.1 DNS1 192.168.20.6 192.168.20.6 DNS2 67.17.215.132 67.17.215.132 DHCP 192.168.20.12 NA 2 Disabled Asustek Server loaded 2008 STD Server (fresh default load) The Asustek server is connected to a cable modem, this is all there is on my side, nothing else. The Gateway, DNS's, the DHCP server are all on the ISP's side. Now the trace route to 172.17.0.1 Tracing route to 172.17.0.1 over a maximum of 30 hops 1 5 ms 7 ms 12 ms 172.17.0.1 now going thru Wireshark and CMD line pings. I have a tracking of 28 pings (7 sets) and only 20 (5 sets) show up on Wireshark, the last 8 pings (2 sets) fail. if there is some means to get these to you, E-mail, I can set up a FTP server, or you can remote in? hami

Ok, so your network diagram looks like this (http://i52.tinypic.com/eiwa6g.png)? If so, there is no need to worry about the 192.168.20.x network. This makes things very simple. To summarize, a DHCP or static IP address should not affect your ability to access the gateway. Here are some new comments...diregard the previous ones. 1) on the server, the gateway's (172.17.0.1) MAC address must be listed in the arp cache (arp -a) 2) Make sure the server has the correct and up to date Network Driver. Check with the vendor. 3) Make sure you do not have a faulty network cable. A faulty network cable could result in intermittent issues. 4) Make sure you do not have an issue with the switch/router network port. A bad port or port mismatch (Autonegotiate/Autosense) could result in intermittent issues. 5) PING uses ICMP. ICMP is usually treated with the lowest priority by network switches and routers. A failed ICMP does not mean that there is an actual issue. However, I do not think this is your case. You clearly have another issue. 6) Does this problem happen with another network card? Can you plug in a different card/brand of card and see if the problem is reproduced?Visit: anITKB.com, an IT Knowledge Base.

Ok 2) All drivers are up to date. 3) there failures are tied absolutely to the changing from DHCP to and from Static, no cable issue. 4) there is one cable from the Asustek to the modem. 5) They are the black sheep in the network world, but there is another problem. 6) Even better it happens with another box, nothing similar than Operating System? Did you get the part about the traces, I sent out 28 pings and only 20 were captured by wireshark leaving the system ! I have the trace files. Hami

I just moved a xp box in the place of the 2008 server, and it has no problems connecting and maintaining connection. Hami

Replacing the box with another computer is a real good test as you have determined that there is nothing wrong with the network or modem. So it appears that the problem is tied to that server. I can tell you that there is nothing special in a configuration that needs to be done when switching from DHCP to static. If you have hard coded in the correct settings, IP, Subnet Mask and Gateway, then you should most definately be able to send simple PING packets back and forth. If that is not happening, there is something wrong with the driver, TCP/IP stack, or some weird failure in the OS. You can try to remove the NIC device from Device manager. that has worked for others in the past for similar issues. If you have another Network Card, I would install it and try that. If it continues to fail, that rules out the NIC and driver concern. With most problems, at some point in time you may have to decide to wipe the system and do a clean install. I think this issue has been thoroughly investigated. You may or may not be able to find the culprit. If you feel like you want to invest additioanl time, try to install another NIC with new drivers. Other than that, I would probably clasify this issue as an Outlier. I wish I could provide you with more feedback. I would be interested in knowing what the issue is if you do come accross a final solution. Visit: anITKB.com, an IT Knowledge Base.

Current status. Loaded 2008 R2 on other partition, and responds the same, I added a XP box to the subnet and it seams to work fine. So the question is how dose XP/2008 handle DHCP/Static differently. I going to burn 2008 R2 and load XP on the same box for more of a comparison. Will get back after install Hami

I have had almost this exact same problem and at this point I believe it to be something with a core OS function or the NIC itself. I think all of the analysis of route tables, etc., is essentially not related. In my case, I have Windows 2008 Server (64 bit) running on a Gateway PC (I know - not optimal...) that has an onboard Realtek RTL8168 Family PCIe GB adapter. Upon installation of the OS, the device showed up correctly recognized by name in Device Manager, but with an error condition relating to the driver. I installed the only compatible driver I could find, a Vista 64 bit driver directly from Realtek's site. The card works, but with this mysterious behavior. When the card first initializes with the new driver, it is obviously by default a DHCP client. The card leases an IP from my DHCP server without incident and I have full connectivity (local and remote) with no issues. However, I want to use a static IP for this server. So, I configure the static address I want - all parameters such as gateway, DNS, etc. checked again and again and only have "local" connectivity. In my case, I can ping the gateway, ping DNS, even resolve external names via nslookup without any problem - but still only "local" connectivity. The ONLY way I can get this to work as I want is if I make the assigned static address the EXACT SAME address as what was originally assigned to it via DHCP. Then, I have full connectivity. It is crazy and completely without logic. I went into my DHCP and put in an exclusion range to keep it from issuing this one "good" address to any other device. It's almost as if somehow the original DHCP acquired address is somehow bound to the NIC permanently. Maybe something with the chipset of this particular NIC? I'm glad it works now, but it's a little inconvenient to have to assign a static from within my DHCP pool of addresses.

This issue shouldn't be troubleshoot any longer as an IP Configuration, or routing issue. There has been enough testing and discussion, in my opinion, which indicates that the issue is a problem with the OS/Driver combination. I suspect that when XP is loaded on this computer, all will work as expected. If it does not, it could be a hardware issue. The typical troubleshooting process deals with IP config first since its easy to check and that is were most of the errors are found. Visit: anITKB.com, an IT Knowledge Base.

Sound pretty much the same to me, but after a few min the pinging of the gateway goes away. So check it again. It is my understanding 2008 and vista share the same base core and the drivers work, just as 2003/XP, and 2008 R2/Windows 7. Ok I reloaded the same system with a copy of XP Pro and it runs fine with both DHCP and Static addresses. So Far it point to the OS (2008 Std Server) Oh, my other server used realtek Nic's, it was the same, this one uses Marvel. Hami

Jm so based on this how can we get this thread moved to a OS forum, there needs to be the history? Hami

A moderator can move the thread. However, if you open a new thread, you can at least reference this one by the URL. Since the problem does appear to be OS/Driver related, I would try to use an Intel, HP, or other similar brand for production servers. If changing the NIC works, its clearly a driver issue. You would then have to take up that issue with the vendor. One thing that is important for Windows Operating systems is to make sure the hardware you are using in on the Hardware Compatibility List (HCL) and its certified for the OS. The cards you are using may not be. http://www.windowsservercatalog.com Visit: anITKB.com, an IT Knowledge Base.

JM The box is a Asustek Server. I had originally believed it was assembled here, but it was purchased directly AsusTek. It is certified for 2003. Hami

I saw your other threads, and frankly, I'm not sure which to post a response in, so for simplicity sakes, I will keep my responses here. It appears that most things have been addressed and tried with help from JM and others. The only thing I couldn't find in this thread, unless I missed it, is what is being used as a DHCP server (192.168.20.12), one of the hardware routers or is it a DHCP server? If a hardware router/firewall, are there any rules blocking any IPs not in the pool? Is it possibly something like QIP or MetaIP?
