First of all, my mistake on the naming. I realized as soon as I posted. =)
Second, while it's nice that SEP 11.x fully supports 64bit OS's, 10.x is what I currently have licensing for and will probably be the only thing I have licensing for for the remainder of the year (budget constraints). For the third and fourth quarter, we will most likely have a limited number of Win2k8 R2 servers rolled out, so I think I am fairly comfortable with the Win2k8 R2 servers going to the internet to get 10.x virus updates.
So this brings me back to my original query, while 10.x (specifically 10.2) does seem to support Win2k8 R2 albeit in a limited capacity, why do I not have the ability to deploy Win2k3 Sp2 agents? The specific error message that I am getting when trying to remotely install is as follows:
"The server (HostServer32bit) is not hosting any compatible Symantec AntiVirus (SAV) 32 bit installers for the 32 bit client (ClientServer32bit)."
Vikram, your post was helpful!
