GroupWise 6.5 Timeout issue...
Posted on 2005-03-01
We have implemented GroupWise 6.5 within our Wide Area Network. It is working great, with the exception of one office within the WAN. This one office keeps experiencing slowness when using the GroupWise Client. What happens is, their client works fine...until they leave their computer sitting for a short time. When they get back to their email and go to open a message, they get an hour glass. If they sit and wait approximately 5 minutes, GroupWise will respond again as normal. However, most of the people end the task and restart GroupWise since they are quite annoyed with the wait they have been experiencing from time to time. None of our other offices are experiencing this issue, and these offices are all set up the same. We are a pure-IP environment running Netware 5.1 SP7 file servers and a full T gigabit network. Our clients are all running Windows 2000 Sp4. Some unsuccessful attempts have been made to fix the problem listed below:
Re-install the GroupWise Client
Re-install the Netware Client (4.9 SP2)
Installed the latest GroupWise Client Service Pack (4)
Had the client authenticate to the GW server through internal IP addressing, external addressing, and URL addressing
Swapped out our gigabit switch to megabit
Swapped our file server's network card to megabit
Checked to see if there were any conflicting MAC/IP addresses through arp
Adjusted Antivirus settings to not scan email
Updated all critical patches on the Windows 2000 platform
The only difference between this office and the others is that it hosts the patch management server for the WAN...so I disabled the server to see if it was causing too much bandwidth
Ran a packet sniffer to check all packet traffic...everything seemed normal except found quite a bit of chit chat from old machines and printers using IPX...disabled those machines and printers from running IPX.
