If you are not hard coding the Switch, which means they are Auto-Negotiating, then you should leave the Servers Nic's at Auto to get best negotiation. I've run into the same problem many times, both sides of the connection shoudl be set the same if auto on one side then auto on the other.

They were very helpful and also suggested another hotfix which replaces the mrxsmb.sys and rdbss.sys files for updated versions. The mrxsmb.sys/rdbss.sys update provided a minimal improvement. I have checked DNS and disabled the anitvirus - again no imrpovement. I have messed around with the speed/duplex on the NIC and found that even hard setting to 100/half gives about the same performance. Setting to 100/full clows it down even more. I do not have managed switches so I reckon the next step is to swap out the NIC and use a different switch. But the thing that still confuses me is that for my test data: data server to citrix server - 15 seconds, citrix server to data server - 5 mintues Thanks for the answers Kev -----Original Message----- From: Dogers [mailto:dogers@xxxxxxxxx] Sent: Fri 03/12/2004 11:12 To: thin@xxxxxxxxxxxxx Cc: Subject: [THIN] Re: Ver slow data transfer XP FR3 on W2003 On Fri, 3 Dec 2004 10:53:56 -0000, Kevin Hopley <khopley@xxxxxxxxxxx> wrote: > This affects file/save routines and logging off where roaming profiles are used - regardless of the logged on user and associated rights.
