Windows 7 file copy extremely slow

I have a Win 7 machine trying to bring a simple 55Meg file across from a mapped drive off an SBS 2003 server. It CRAWLS through discovery and then says it will take 2 HOURS.

The strange thing is the copy even hangs when you go old school and use copy, xcopy, etc at the command prompt.

Has anyone come up with a definitive answer for all this Win 7 file transfer slowness??  I have other Win 7 machines on different networks with an SBS 2003 server and I do not have this problem.

I have tried all the int tcp set stuff.

Thanks!

Do you have Windows 7 updated to Service Pack 1?  SP1 fixed some slowness issues (not necessarily yours). Also is your server fully up to date?

Look at http://support.microsoft.com/kb/926505 (it is about joining a domain, but see if the update helps)

Look at http://support.microsoft.com/kb/2570623 for slow Excel files.  

I use Windows 7 with SBS2003 in a variety of client locations and do not experience undue slowness.

Yes thank you every possible update is applied. I even disabled the antivirus programs and no difference.

See if you can find a different Windows 7 machine for *this* network to see if it that one machine (maybe rebuild it) or whether it is all Windows 7 on this particular network. ... Thinkpads_User

I would check all the hardware and connectivity of the slow machine between it and the server...

Is it ethernet or wifi?

Make sure a good, solid connection between the two machines exist...

Verify either with ping or tracert to see if there are lost packets, slow latency or wierd routing between them.

Remote Differetial Compression is ON by default in Windows 7. I have it set ON and it does not cause any slowness with file copy (my machine or clients so far as I know).  Let us know in your case. ... Thinkpads_User

That is what I thought. It makes no difference in speed in my Windows 7 systems (which are not slow to begin with).  Can you try a different Windows 7 machine on this particular network. ... Thinkpads_User

For some reason the NIC is adjusting itself downward to 10BaseT speed. Need to investigate, but adjusting it back up fixed the prob. Thanks for your committment and help

Thank you. I was very pleased to assist you and thank you for the update on the NIC. I do not usually see NIC's adjust themselves like that, especially on newer Windows 7 machines.  ... Thinkpads_User

I have seen this a few times in the last year. Cat 6 cable, gigabit switch on the other end, network performance for the workstation goes down hill (including the infamous Windows 7 "not responding") and I find this problem. I am going to start looking at this first each time.
