Windows 7 random issues copying to network drive

[gec5741]

I have a win 2008 server setup as a domain controller. I have 2 winXP boxes and have just installed windows 7 x64 on a 3rd machine. I get all my drive mappings fine when I log into the domain on with the windows 7 machine. I can save small files fine but the problem started when I was copying large video files over to the server. At first the windows 7 machine would instantly lock up when trying to copy large files. I read that there was an update so I did windows updates and there was an update for my network adapter so I let it do the update. The locking up has stopped since then but I can very rarely successfully copy a large file to a network drive. Probably 9 out of 10 times I will get a message that say's I don't have permissions. It can't be a permissions issue because I can copy anything fine as the same user on any other machine. Just since I installed windows 7 has this issue come up. Also it will allow me to copy a large file once in a while but most of the time I"ll get a permissions error.

I downloaded the latest win7 chipset driver for my system board from asus and ran it. If I try to update my lan driver it tells me that it is currently up to date.

Any help I would greatly appreciate it!

It seems like you are facing issues with copying large files to a network drive from a Windows 7 x64 machine that is part of a domain with a Windows Server 2008 domain controller. Here are some troubleshooting steps you can try to resolve this problem:

Troubleshooting Steps:​

1. Check Network Connectivity:
   • Ensure there are no network connectivity issues between the Windows 7 machine and the server.
   • Test network speed and stability by transferring files between different machines on the network.
   []Check File Permissions:
   • Verify the file and folder permissions on the server. Make sure your user account has the necessary permissions to write to the network drive.
   • Check both share permissions and NTFS permissions on the server.
   []Update Network Drivers:
   • Although you mentioned updating the LAN driver, it's worth double-checking if there are any newer driver versions available from the manufacturer's website.
   • Consider uninstalling the current network adapter driver and then reinstalling it.
   []Disable Large Send Offload (LSO):
   • Large Send Offload can sometimes cause issues with large file transfers. Try disabling LSO on your network adapter:
     1. Go to Device Manager.
     2. Locate your network adapter, right-click, and select Properties.
     3. In the Advanced tab, find the property related to Large Send Offload and set it to Disabled.
   []Check Antivirus/Firewall:
   • Temporarily disable any third-party antivirus or firewall software on the Windows 7 machine and attempt the file transfer again to see if they are causing the permissions error.
   []Disable Remote Differential Compression:
   • Disable Remote Differential Compression (RDC) to see if it resolves the issue:
     1. Go to Control Panel > Programs and Features.
     2. Click on "Turn Windows features on or off."
     3. Uncheck the box for Remote Differential Compression.
     4. Restart the computer.
   []Clear Cached Credentials:
   • Clear any cached credentials on the Windows 7 machine that might be causing authentication issues:
     1. Open the Credential Manager.
     2. Remove any credentials related to the server or network drive.
     3. Restart the machine and try copying the files again.
2. Test with a Different User Account:
   • Try logging in with a different user account on the Windows 7 machine to see if the issue persists. This can help identify if the problem is user-specific. By trying these steps, you should be able to troubleshoot and resolve the issue with copying large files to the network drive from your Windows 7 machine. Let me know if you need further assistance!
