Looking for some Exchange knowledge. Last week admin ID's for nodes were being 
removed and it was discovered 2 days later that this broke the Exchange 
backups. Once they were put back backups started working again but what 
confuses me is when comparing 2 different sites things seems to work 
differently as it relates to Exchange.

I have no access to the client side, only the TSM server, so I can't relay 
anything except what I see here. At one site the nodes are set up just like any 
other node it looks like. Licensing shows 2 Exchange TDP in use but when 
looking at q no the platform shows WinNt. These nodes do NOT have an associated 
admin ID that I can find and backups work just fine. Why things report the way 
they do I don't understand.

The second site licensing shows 6 Exchange TDP in use and q no on these show 
the Platform as TDP MSExchg. These nodes are also configured with Proxynode 
Agents too whereas the first site is not. Why this I don't understand either. 
Since I don't know much about Exchange backups in general I would have assumed 
based on the first site this would be the normal way they would be set up.

This second site is the one that Exchange backups stopped working when the 
Admin ID's were deleted. I put everything back and backups work now but when 
looking at the admin ID's it seems as though only one of them shows Days Since 
Last Access 1 so I don't know if removing the others would break this again or 
not. Support told me these Admin ID's need to be there for Exchange to work but 
this doesn't  seem to be the case at the site that works where are no admin 
ID's there are not associated with an Exchange node.

Hopefully someone has some explanation for this.

Thank You
