SYMPTOMS
When you use all numeric NetBIOS computer names, some TCP/IP utilities will misinterpret these NetBIOS names as IP addresses.

For example, if you have a computer named 4754755 and its IP address is 10.1.5.17. When pinging the computer, ping will misinterpret the computer name as an IP address and will send an echo request to 0.72.141.67 rather than 10.1.5.17. This will result in a request timed out error.



RESOLUTION
The use of all numeric NetBIOS computer names should be avoided when you are using the TCP/IP protocol.



STATUS
This behavior is by design.
