I just upgraded our Netware server from sp3 to sp6 last night. Didn't really detect an issues initially after the upgrade. I installed the manadatory cifs and edirectory updates and the recommended tcp update. I'm pinging the inside address of the server and occassionally notice some really high latency times...ranging from 1000-2500ms for about 10-15 seconds and then it goes back down to under 1ms.
The server is running as a file server, Groupwise, Intranet (php and mysql), and is running arcserve. It's used by about 25 people inside the office and externally by about 25 people via ssl vpn.
Any idea what would cause the latency and how i can determine where it's coming from?
