Michael, worked with my network team, what we had originally is the request hit the ISA and then the ISA had the tick to say all traffic looks like it is from the ISA, then it went on in to our core FE servers, I have removed that tick so now I have a 75.x coming into the ISA and trying to hit the FE servers which of course is not allowed by the firewall....is this what you were referring to about the asymmetric routing, am I going to have to have this look as if the 75.x is going all the way to the core???

That is, your IP path in is the same as your IP path out. Could be your ISA, could be your NLB, could be both. Regards, Michael B.

Looks to be on the FE/BE, not ISA, but no real reasoning as to why it is not working. RPCPing is working, the certificate is homegrown for the time being but is installed on the FE servers, the ISA servers and the workstation. Any suggestions or places anyone can think of to look???
