Same subnet? We’ve had some periodic issues with RPC on Windows 7/2008 R2 due to IP6 not routing on campus.

I do not have RPC pinned down, but I have also tested both machines with the firewall disabled… There are no other firewalls between the two machines.

 

Same problem.

Sounds like a windows firewall issue.  Windows 2008 R2 and Windows 7 both have good firewall tools that are worth getting to know and I also use Microsoft’s Log Parser to check whether certain ports are being blocked.

I've had this before… and I don't recall doing anything to fix it.  It just started working one day… not sure why…

 

So, I have a new HyperV server in place.  Not clustered… just one of 3 that I have.  The 3rd is just used for testing some things… eventually maybe some clustering?  Well…  here's the deal.

 

I use Windows 7 and the Server Administration Tools for Windows 7.  I can connect to the HyperV server just fine with the HyperV manager.  However, I always get the pesky "Cannot connect to the RPC service on computer "blah".  Make sure your RPC service is running.

 

Using the MMC, I can connect to the machone remotely and see that the RPC service is, indeed, running.

 

Online searching leans towards DNS issues, but there is a DNS entry, and reverse lookup record, for this server in DNS.  

 

Anyone run into this and know how to fix it?

 

Thanks!
