MBSA Microsoft Baseline Security Analyzer not scanning all pc's

I keep getting the following responses for each pc that MBSA is trying to scan:
Computer not found.
Could not resolve to computer name.

I can ping the computers by name, so DNS is resolving the name. And I get successful replies from the computers, so IP connectivity is working.

Does anybody know what this could be? Could it be that the Microsoft Firewall on the target computers is preventing the scan?

Thanks

It could be possible that DNS is not resolving to correct IP address.

Sometimes, DNS does not update quick enough and you see incorrect IP and Name pairs.

Have you check if the machine name is resolving to correct IP address or not.

To do this, ping the machine by name.(You will get the IP address).

Now go to that machine and check the IP address by ipconfig.

They should match.

The firewall sounds more likely, especially if you put the IP into the mbsa and use the IP rather than the DNS name. The MBSA also requires admin priv's on the pc it's scanning. The firewall on XP Pro is turned on automatically when SP2 is applied.

Prashax. I stated that DNS works when I ping the target computer by name. So that is not the problem.

Rich. You are probably correct. So does that mean I have to go to each machine and disable the firewall to run MBSA? Maybe I could use Group Policy to temporarily disable the firewall, run MBSA, then re-enable the Firewall. MBSA must have come out before the XP firewall for this to happen.
