Hi I recently accepted a network admin position at a small non-profit. Here they have 3 servers, email is handled via a Windows 2000 server running Exchange 2000. For the desktop client they use Outlook 2000. There are a variety of PC's some old with as little as 64MB up to newer machines running about 192MB +. PC's are running anything from Win 95, to Win 2000(yes I have a lot of work to do standardizing here. <grin>)

I've come across an issue that at first I thought was simply a memory issue, but I've got a PC with about 90MB starting to exhibit the problem. Actually there are two issues here. My Exchange 2000 experience is small so this is a learning experience for me.

The first issue is that some of the PC's when launching Outlook will after about 20-30 secs get an error that the Exchange Server is unavailable. However when they choose retry they connect after a short wait. It's not EVERY machine (actually none of the Windows 2000 machines do it, but I've seen the 95/98 machines do it... and even then not all of the 95/98 machines do it.

The second issue is more troubling it happens on a variety of PC's here 95/98 and 2000. The PC's will have trouble opening email that has attachments(regardless of whether it's a small word document, pdf or a large photo), and will simply freeze. Even if you try to simply launch the attachment directly from the main window Outlook will freeze. In addition the same PC's that exhibit problems with attachments also exhibit problems opening and responding to emails that have been written using HTML.

I'd appreciate any thoughts on what I might want to look into. Thanks.
 
Well, off the top of my head, I would have a look at dns. Do the pc's pickup there ip addresses from dhcp or static? Do the pc's dns addresses point to the internal dns server? Also, is it possible it's a hardware problem (All the pc's in question connected to the same switch)?

I would run several pings and nslookups on the pcs in question and the dns server. Try starting and stopping (or maybe even rebooting) the server that hosts dns.
