My servers are currently running IIS 7 (windows 2008). Is there any way to get IIS 7.5 without upgrading to 2008 R2?
The reason I ask is that they are 32 bit servers and there is no upgrade path from 32 bit 2008 to 2008 R2.
Nope. You basically should never have installed 2008 32 bit for an IIS server. Microsoft made it pretty clear back then that this would be a dead end. ;)
