windows 2k3 e2k3 sp1 cluster - dual proc (hyper-threaded) 3GB RAM clients - outlook 2k3 (cached-mode) - most of them
We're having a problem on one of our mailbox servers where outlook gives the infamous message "Outlook is requesting data from the server Or Outlook is trying to retrieve data from ". Uniquely enough, it happens to our cached mode as well as live mode clients. My suspicion is that there are network problems with this machine (switch, card, line, etc.) When I checked the server during this occurrence, the processor was pinned at 100% with the store process utilizing the most. It stayed in this state for almost 2 minutes straight, before dropping down to the 30-40% level. There were no backups running, and I tried to search to see if anyone sent any unusually large messages to a bunch of people - this wasn't the case. I had turned up logging on IS and there are two things that I found: The first is that a lot of clients are performing OAB downloads (we had the clients configured for this fairly frequently during the migration from Groupwise - this will be changed, but I don't think that this is the core of the problem) The other information that I kept getting was this: Only 72% of user 's 37 attempted RPCs have succeeded in the past 14 minute(s) (which is less than the threshold of 75%)). Adapter Speed: 10000 kbps Machine Name: xxxx.domain.com Client Mode: Cached This last message indicates to me that there might be some network problems. your thoughts would be appreciated.
