Apple Airport Time Capsule NETBIOS name

leave a comment »

After setting up an Airport Time Capsule with the default base station name of “AirPort Time Capsule” I found that I couldn’t connect to it from a Windows PC using a NETBIOS name.

An IP address worked OK, e.g. I could open \\192.168.0.11 in Windows Explorer and see the Data network share. But any attempt to use the base station name, even enclosed in quotes, failed:

C:\>ping "AirPort Time Capsule"
Ping request could not find Airport Time Capsule. Please check the name and try again.
 

A quick search on NETBIOS names showed that the maximum number of characters is 16 but that Microsoft reserves the 16th character. So, I tried NETBIOS names of fifteen and sixteen characters, e.g. “AirPort Time Ca”, but this failed too.

Knowing that some NETBIOS implementations, including Microsoft’s, can be fussy about characters such as spaces, I guessed that Apple probably uses a NETBIOS name based on the base station’s name but limited to fifteen characters and spaces replaced by hyphens or underscores. So I gave this a try:

C:\>ping "AirPort-Time-Ca"
 

and was rewarded with:

Pinging Airport-Time-Ca [192.168.0.11] with 32 bytes of data:

Success!
