Exchange going really slow - outlook exclamation mark!
Posted on 2008-10-17
We have exchange 2003 running on server 2003 R2 across two sites, one domain. Was running fine until last week when people started getting "outlook is trying to contact exchange server" exlamation error. CPU was fine as was memory. We defraged just in case overnight but still no difference.
Then, by coincidence, we had to reboot our DC for the site. (which is also the GC). Immediately exchange recovered and was lighting fast. Since then we still get slowdowns, but these are immediatly resolved by rebooting the DC. Error logs don't seem to show anything untoward and now at a loss to explain/fix it..................
