did you  use the nbstst -n command
It appears that there is a machine with the same name
a ways to resolve, find change the machine with the conflicting name and change it

1. If two computers on the Network with the same name, use the nbtstat -n command to find out these two computers, for example, using nbtstat -n to check the name and ip of the local computer, and then using  nbtstat -a command with the IP address to get the another computer name.
2. If identical username is logging on to multiple computers, the usernames will register with a <03h>, and that may cause the name conflict in the network. Ask the user to log off of all computers and log back on to just one computer.
3. This may be occurred because of inactive or duplicate names in the WINS Database. Go to the WINS server, check the database and delete the inactive or duplicated names.
4. This my be  occurred because of  a possibly corrupted DHCP database. To clear DHCP related entries or clean out old settings in the registry, delete any .mib files, and then reinstall DHCP.
5. This may be occurred because of  conflicting NICs in a Multihomed Computer. To fix this problem, you may want to stop Computer Browser service or uncheck one of Client for MS Network.
6. This may be ocurred because IPCONFIG /ALL returns incorrect host name. To change computer name in the TCP/IP parameters section, run regedit.exe, and locate the HOSTNAME value in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip \Parameters, and then edit the string data.

One place to look is in the DHCP server to see if there a computer with 2 IP addresses.  You may also want to look in DNS server for computer that registered 2 IP addresses.

This Domain Server is active with 2 NIC cards with 2 different IP's 192.168.10.14 & 192.168.10.33...
Should I uncheck the client for MS Network on both NIC cards?

Thank you,

bradleys40Commented:
This is a whole new question

to resolve your current issue change the setting client for MS Network

its up to you but, personally i would set up nic teaming but this is a subject you neeed to read up on in relation to your server, you need to understand what you are doing and be comfortable with what it is doing
the server will manage the faul tollerance and you wont have any conflict issues
