We run outlook 2007 over terminal server 2003 and have suddenly begun experiencing intermittent lag on all clients using the application. Details below:

• HP router upgrades implemented at the same time issues began have been rolled back, no resolution.
• No PST's stored on roaming profiles.
• Terminal server NIC drivers up to date and varied in terms of version.
• Re-installed MS office on example server, run with no SP, SP1 and SP2, no resolution.
• Network sniffer reports out-of-order packets. reassembled segments of PDU and duplicate ACK's. After being analyzed by our network engineers concluded irrelevant.

We have a ticket open with Microsoft that is getting us nowhere, more information can be provided upon request.

Any insight would be infinitely appreciated as this has seriously stifled our work flow.

Thanks,

Ben
