Situation: After migrating a computer from windows 2008 R2 to 2010 R2 server, some users can’t map the server by using NetBIOS hostname, for example server1.
Troubleshooting: 1. The server has multiple IP addresses.
2. They can’t ping the NetBIOS hostname.
3. Ping FQDN works.
Resolution: Add server main IP address to hosts and lmhosts under C:\Windows\System32\drivers\etc, for example 10.0.0.2 server1. Run nbtstat -RR or restart the client’s computer.
