I configured exactly like this and did not run into a any problems until I tried to deploy task sequences. When I do I get the error message in Software Center:
"Unable to make changes to your software"
More information just tells me:
"The software could not be found on any servers at this time"
I did some poking around and everyone is saying it is a Boundary issue. I have all my IP subnets as boundaries (x.x.x.0 for example) and added to the boundary group. Any help? Thanks in advance!
