Failed to connect to the service manager on ""

I'm trying to setup a cluster on 2008 server r2 servers. They are the same spec. I get the error: Failed to connect to the service manager on "" whenever i run the validation wizard from server01. However when I run it from the other server it passes fine.

Both firewalls are disabled. How can i fix this.

Could it be hardware or bios related?

Case 1: The remote server has name resolution issue can't be connected.
Case 2: Firewall blocks the connection.
Case 3: The client change the IP address and need to flushdns.
Case 4: Can't access the server because it has been moved to different subnet.

None of these help. Could some parts of the firewall still be on even though I disabled it?

I created shared folders on each node. I notice when i go to my network detection and click on the local server it works but when I go to the other node and try to access the shared file on Node A then it times out. Every once in a while it will not time out and I can access it but it takes a long time.

Then try running a Best Practise Analyzer for Windows 2008 and see what's going on Run it both from Node A & Node B and compare it and see

Hope that helps :)

Quick Tip - Try the Network Discovery Settings on both nodes and check whether it is set to discoverable mode.

Clustering is a feature and not a role so I can't run BPA. Tried putting Network Discovery on. I succeed in enabling it but this did not work either.

Something weird is going on because earlier I was able to run the validation tool and it worked fine when running it from Node B but when i ran it from Node A it gave me the Failed to connect to the service manager on ""

I decided to restore both servers each from their original image before they were on the domain. So they were both just work group servers installed from CD with all updates downloaded.

So they are both clean. I joined them to the domain and now I can't even get either to connect regardless from which server i run the validation tool from. During validation attempt from each server each detects itself but fails to connect of service manager of each other.
