Nate, In my case all of the desktops are new (less than 6 months old) Compaq Deskpro EN's PIII866 upwards, 128Mb memory and oodles of HDD space available. Protocols are all IP and bindings are fine. Attachment sizes are below 2-3Mb. Mcafee Vscan is used on all desktops - updating via FTP to my FTP server on the WAN.
No PST's (I'm not that masochistic!) and PING, tracert show nothing to worry about...

What about the desktops we are dealing with? I haven't seen any information on them in your entries so far (have I missed anything?). What about binding order on the desktop? Make sure either RPC or TCPIP is first in line? How big are the attachments being opened? Are they larger than normal? What antivirus software is being used on the desktop (you do have AV software running on the desktop don't you?)? Do your users have PST's (PST=BAD)? If so, how big are they (on average)? What about network connectivity from the desktop (how are the PINGs during this peak time?). Regards.
