I have the same issue with several clients. XP Pro to XP
Pro and/or Windows 2000 Server. Copying and printing is
extrememly slow and can time-out. No luck with any fix
suggested by MS via TechNet. I have tried disabling SMBs,
Security sigs, adjusting NIC adapter timings etc.

My gut feel is that it has something to do with security
checking of each packet that XP is sending. (Challenge-
Response?)

I tested with CA Brightstor Backup and a 140mb database
file backs up in <60sec vs a file copy at +8mins. The
file copy was attemtped using Explorer and a CMD window.

As this issue affects many people, I hope Microsoft pay
some serious attention to resolving it.

If anyone has solved it, please let MS and the Usergroup
know how.

Thanks
