Type 'hostname' to return the name of the system:
c:\> hostname
If the hostname command returns:
get hostname: unknown error number
Type ipconfig to return the IP address of the system:
C:\> ipconfig
Windows NT IP Configuration
Ethernet adapter El90x1:
IP Address . . . . . . 198.102.62.22
Subnet Mask. . . . . . . : 255.255.255.0
Default Gateway. . . . . : 198.102.62.25
Look at the 'IP Address' line for the current IP address of the computer.
Ping the hostname
C:\> ping server1
Pinging server1 [198.102.62.22] with 32 bytes of data:
Reply from 198.102.62.22: bytes=32 time<10ms TTL=128

If the IP address returned matches the IP Address returned by the ping command, the local TCP/IP name resolution is functioning properly.
If the IP address returned by step 2 does not match the IP Address returned by the ping command, then name resolution for the system's hostname is incorrect. Contact your Network Administrator to correct the problem.
If ArcGIS is attempting to check out licenses from a remote license manager, execute the ipconfig and ping commands on both the server and the workstation. In this example, the hostnames are workstation1 and server1.
Run these commands while on the workstation.
D:\> ipconfig
C:\> ping workstation1
C:\> ping server1
Run these commands while on the license server.
C:\> ipconfig
C:\> ping server1
C:\> ping workstation1
The IP address for the workstation should be identical when ping is performed on the workstation and the server. This is also true for the server. If a command returns a different IP address for a particular machine, TCP/IP is not functioning properly. Contact your System Administrator.
