UNABLE TO access network share

My customer has a 2003 pdc (\\mammoth), a 2003 domain member with exchange and a dozen xp workstations. They have experienced problems recently with sql server on the pdc which have now apparently been resolved after deleting a corrupted database. Most workstations can access the SQL application. The SQL application requires access by name - \\mammoth\mamut' Two PCs cannot access the application. They can see the shares as \\\mamut but not as \\mammoth\mamut. They can see other shares on the 2003 member server and on xp PCs. The server can see a share on the problem PC as well.
Since the problem started a week ago the PC was generating frequent errors 10009 for the server //mammoth. Since I have been looking at it, today, it has now stopped, but it is still not possible to access the server share. I have googled for various suggestions but made no difference

10009 - DCOM was unable to communicate with the computer mammoth using any of the configured protocols.

Sounds like a DNS issue.  On the systems not working - try from the command line the following:

ipconfig /flushdns

Then try pinging the share name (ping \\mammoth\share$)

If it resolves to the correct IP, your DNS is working properly and you may have some other issue.  Let me know if it resolves correctly but still can't map - but if it resolves - you should then be able to map to that drive either from My Computer, or the command line.

Thanks for the response, I could not ping the server and flushdns did not help. While looking at this, it occurred to me to check the hosts file. It had the wrong IP address for //mammoth. The serer has two lan cards, one was not being used and I suspected it was the cause of poor dns resolution so I disabled it. The PC with the problem was pointing at the disabled IP instead of the correct one!
