I have A windows 7 computer, with other Vista and XP computers on a network. I use MSHOME as the doman. I have disabled firewalls, I have disabled Ipv6 on the Windows 7 computer. I use no password on the network. I have to reboot my Windows 7 computer several times a day because periodically it will block out the other computers and equipment on the network. A reboot will allow everyone access again for a couple of hours, then boom, no one can access me. I get the "you do not have permission to use the resource" error. Once I reboot, all the other computers have access for a few hours, 6 hrs, sometimes up to 8 hrs, then all of a sudden, no one can get into it and I'm forced to reboot. The computer is about 8' from the router and no other computer loses connection to the network. I am sure there are no network issues on the hardware side of things. Obviously, the basic settings are correct, as the other computers do have access for up to 8 hrs at a time. When they lose connection, I can still connect fine to their computers, see them onthe network map, etc. Are there any reasons this could be happening?

1. Are there any traces in Event logs? 2. What does say nbtstat ? 3. Have you tried to forth SMB 1 in W 7 & Vista? Rgds Milos

Hi, Please check the Event Viewer for the error message. In addition, you can try the following: 1. update your router firmware to check the result. 2. Disable Autotuning: Open CMD as administrator, and input the command: Netsh interface tcp set global autotuning=disabled 3. Disable remote differential compression: Open Programs and Features, remove the feature Remote Different Compression Hope this helps. Vincent Wang TechNet Community Support

I don't see any info in the event logs and I have no clue what your other two answers mean. Sorry, maybe this isn't the right place I should be asking this, because I may not be technical enough.

Hi, For detail steps about Disable Autotuning: 1. Click Start, click All Programs, and then click Accessories. 2. Right-click Command Prompt, and then click Run as Administrator.

Close the Command Prompt window. 5. Restart the computer. Regards, Vincent Wang TechNet Community Support
