I have a Windows 2003 R2 Enterprise Edition SP2 that is a domain member server acting as a File and Print server for Windows XP and 7 clients, and having 2 win2008 R2 domain controllers. Some clients randomly cannot connect to the file shares, can't print, and sometimes I can't remote desktop or even ping it. When these disruptions occur, come clients can connect and some can't. I have installed a replacement network card and replace the network cable. I otherwise do not have any network interruptions on the network: Event Type: Error Event Source: NETLOGON Event Category: None Event ID: 5783 Date: 1/24/2011 Time: 9:55:44 AM User: N/A Computer: FILE-SERVER Description: The session setup to the Windows NT or Windows 2000 Domain Controller \\dc1.mydomain.local for the domain MYDOMAIN is not responsive.

Hello, start with: http://support.microsoft.com/kb/938449Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

This article is about having this error on startup. I don't have this on startup, I see this error randomly while the server is up and running.

Hello, you can try resetting the secure channnel: http://technet.microsoft.com/en-us/library/cc788073(WS.10).aspx If this doesn't help rejoin the clients to the domain. Are the clients created from an image/clone that is NOT prepared with sysprep?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

I just reset the secure channel as you suggested on the file server. No winXP clients where cloned. Some Windows7 clients were cloned w/o sysprep (because I haven’t found a simple sysprep windows7 procedure – is there one?), but I haven't seen a correlation between when there are issues if there where cloned w/o sysprep machines having issues. I'll watch how things go over the next few days to see if the secure channel fix helped or if there is a cloned w/o sysprep correlation. Thanks for the advice.

Hello, see here about sysprep in Windows 7: http://technet.microsoft.com/en-us/library/dd744512(WS.10).aspx also check the support policy for clones: http://support.microsoft.com/kb/314828Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

So resetting the secure channel didn't make a difference. I'm still seeing Netlogon errors 5719 and 5783 on a daily basis. The problem seems to be between this win 2003 R2 SP2 server and the win 2008 R2 Domain contollers. None of the errors mentions any client desktop pc issues. Any other ideas to fix this?

Disable any Windows firewall, and/or any third party firewall that may be installed. See if the problem goes away after that.

The File server and Domain Controllers are plugged into the same hardware switch, and have no software or hardware firewall installed between them.

run the folllowing command on each computer netstat -s make sure no errors/failures/discards are being reported. If they are errors/failures/discards then switch cable/card/switch ports.

I replace the NIC and cable 2 months ago, all other equipment on the switch has been fine. It's an Intel Pro/1000 GT Desktop Adapter running Intel 8/20/08 8.10.3.0 drivers signed by Microsoft. Based on this do you think I need to replace the NIC again? any different NIC I should try? <code> C:\>netstat -s IPv4 Statistics Packets Received = 16002704 Received Header Errors = 0 Received Address Errors = 177 Datagrams Forwarded = 0 Unknown Protocols Received = 0 Received Packets Discarded = 301 Received Packets Delivered = 16002226 Output Requests = 12033771 Routing Discards = 0 Discarded Output Packets = 0 Output Packet No Route = 0 Reassembly Required = 0 Reassembly Successful = 0 Reassembly Failures = 0 Datagrams Successfully Fragmented = 0 Datagrams Failing Fragmentation = 0 Fragments Created = 0 ICMPv4 Statistics Received Sent Messages 7089 8173 Errors 0 0 Destination Unreachable 12 1095 Time Exceeded 0 0 Parameter Problems 0 0 Source Quenches 0 0 Redirects 0 0 Echos 5599 1479 Echo Replies 1478 5599 Timestamps 0 0 Timestamp Replies 0 0 Address Masks 0 0 Address Mask Replies 0 0 TCP Statistics for IPv4 Active Opens = 11279 Passive Opens = 43934 Failed Connection Attempts = 2187 Reset Connections = 10073 Current Connections = 56 Segments Received = 15824726 Segments Sent = 11915824 Segments Retransmitted = 45486 UDP Statistics for IPv4 Datagrams Received = 160701 No Ports = 19774 Receive Errors = 1235 Datagrams Sent = 64102 </code>

Ok, i'm out of ideas. Here's the last suggestion i have. Check to see if the following registry key exists, if so back it up (export it to a text file), then delete the key, then reboot. HKLM\Software\Microsoft\Rpc\Internet

I don't have a HKLM\Software\Microsoft\Rpc\Internet key. arg.

Hello, please post an unedited ipconfig /all from the DC/DNS servers the file/print server and a problem client.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Ok, one last idea, round robin DNS or bad WINS. Check your DNS registrations on the DNS server to verify that only one DNS entry is registered, and/or that all DNS entries are correct. Check the WINS entries for this server on all WINS servers. Verify all entries are correct. From any problem client verify the ip address returned by DNS or WINS is the correct one.

Disable all network adapters that have the "Media Disconnected" This is a known issue with mulitple NICs.

Hello, just the problem client is missing. As the Tunnel adapter belong to IPv6 you can try to disable IPv6 complete for testing: http://support.microsoft.com/kb/929852Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

I disabled the IPv6 tunnel adapters so they don't show anymore in ipconfig/all, previously I had just unchecked IPv6 DNS - entries for file-server, dc1, and dc2 both forward and reverse look good and clean, there aren't round robin or duplicate entries. I don't have anything configured for WINS at all. nothing on the domain controllers or clients - does this matter? my oldest machines are XP. I'll watch things and report if the removal of the disconnected IPv6 tunnel adapters acomplished anything. Thanks again for your help.
