Let me apologize in advance for what may seem like a shotgun approach
since I have post this in asset-inventory forum. Since both the
collection and task servers are involved I thought I'd post it here as well.

I'm running Zam 7.5 and last Friday installed the ir4 update following
the readme instructions. Our enterprise has 38 Zam domains representing
remote and local sites. Each site has it's own Collection/Task server
(high end desktop running WinXP. All was fine until the IR4 update. Now
there is approx. 12 Collection/Task servers that appear as unavailable
in the manager. I totally removed one of the servers and reinstalled it
and was able to get it connected. After it connected it pickup on the
upgrade and is working fine now. Will I need to do this with each of the
unavailable servers or is there another way.

Here's the logs after the update.
