Slow access to shared folders, but fast to UNC path?

[Stannerack]

Hi

I have just performed a server upgrade from Windows 2000 Server to Windows 2003 Standard. We have 3 domain controllers, all of which now run Windows 2003 server.

I am having major performance problems when trying to copy files to a network share on one of the 2k3 servers.

For instance, I have mapped a drive letter to a folder share. It takes 10 to 20 time longer to copy a batch of files than normal. If I just open up a window to "\\servername\sharename" the copy is as quick as it should be.

I have uninstalled antivirus, turn off XP settings that search for folders and printers, but no joy.

Does anyone have any ideas?

Many thanks
Paul

Thanks for that.

I had fiddled with the SMB signing, but in the meantime I noticed that SP2 for WinXP is now available for download.

It seems to thave fixed the problem.

Now all I have to decide is whether to deploy it to 300+ workstations or wait for SP2a within the next week or so! ;-)
