I have a PC with upgraded windows 7 home premium 32 bit and a toshiba laptop with upgraded windows 7 home premium 64 bit. I have an actiontec gt724wgr modum and router. PC is connected by ethernet and laptop is connected by wireless. PC can see and access the laptop. Laptop can see but not access the PC. I also share my Office small business with business contact manager between the two computers and I have been able to share the MSS database from the PC with the Laptop. I do take the laptop home and connect to my wireless gateway to get on the internet, but I do not connect to any network or domain at home. There are other computers at home, that also access the internet through the gateway, but there is no network set up at home. I have tried alot of suggestions from other forums but nothing works. The workgroup at work is the same name on both computers, they are both set at home network, all the proper sharing settings are set. I am at a loss. I have removed my McAfee security suite and am only using windows firewall and windows security essentials on both computers

Hi, I would like to confirm that what error message was encountered when trying to access the sharing files on the PC? Please change both the NTFS and the sharing permissions to assign Everyone group full control. Does it work? I also would like to share the following article with you and hope they are helpful!

I do not have much time. I have already reviewed the article and did everything in there. I have developed a work around. Last night I restored my computer to a time about two weeks ago when I knew everything worked and it worked. I then individually updated all the windows updates and turned off both computers in between every update to make sure it still worked. (I thought maybe an update had created the problem.) When all the updates were installed, everything still worked. Then I created a restore point. Then I went home, accessed the internet through my gateway at home. I made sure to manually disconnect my gateway access before I left home, in the hopes that that might work. I came into the office and nothing worked. Both my connection to the database for Business Contact Manager and my ability to access the office PC to see documents and other files was severed. It should be noted that I can see the office PC on the network map, but I just cannot access it. Also, my office PC can both see and access my Laptop at all times. I restored the computer to the restore point I created last night and everything worked fine. I suspect this has something to do with the interplay between the gateway/router I use at home and the one I use at the office. The home gateway is protected by WEP and the office one uses WPA-2 Personal. I suspect that my computer somehow changes some internal setting to access the home gateway that blocks the access to the office PC from that point forward. Not sure if it is because the home gateway creates a domain (I'm not sure that it does create a domain, but my laptop did not have windows 7 when I originally set it up and several other laptops that connect to the internet at home still do not have windows 7) rather than the workgroup/home network system at the office or if it has something to do with a conflict in the WEP vs. WPA-2 Personal security systems. Since I have a work around and I have lost about 25 work hours in the last three days to deal with this, I don't have much time to investigate at this time, but these clues might enable you or someone else to get to the bottom of this problem, because I can see on other threads that this is something many others are dealing with. When I come into the office tomorrow and the same problem exists, I will get the error code for you. Let me know if there is anything else you need. Also, I don't know what NTFS is, but I have given Everyone group control on the office PC for sharing purposes.

I came in this morning and the connection was again broken. I could connect to business contact manager through the network but I couldn't do anything else with the PC--normal problem. The error code was 0x80070035. I restored the computer to the old settings and everything worked fine. See my earlier note below.

It may be a problem with the IPv6 vs IPv4 problem and the 2 different routers. I had to fix mine by disabling IPv6. there are 2 methods: 1. open your network adapter's properties page and uncheck the box next to TCP/IPv6, then reboot. 2. Go here for registry instructions: http://support.microsoft.com/kb/929852 I found out that ipv6 can override ipv4 networks and routers that don't support it, blocking access to the network and shares. Also if you use admin shares & they disappear, The standard setting of Window 7 is NOT to recreate the admin shares at every startup. So i found that setting the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters\AutoShareWks=1 (from its default value AutoShareWks=0) finally did the magic. I have also set the LocalAccountTokenFilterPolicy=1
