Maybe you should consider adding privilaged ports to NT5? That way you can shift ports on a protocol safely if this sort of situation ever arises again. (although you'll probably need to wait till NT4 isn't in common use) > It is NOT totally undocumented, nor is it used for WINS stuff.

The reason I thought it was used for WINS was that when I was trying to decode the WINS replication protocol I noticed that it seemed to start on TCP/135 then move to another port number shortly after. The only thing I had to go on was packet sniffs, so it is little wonder I got it wrong! Does WINS replication use it at all, or did I just stumble down a totally blind alley? Also, do you have a pointer to the spec for the port? It's not relevant to our discussion, I'm just curious about how it works. Anyone from the Open Group have a pointer? Cheers. Andrew PS: I'm sure that there was a bug report a while back that sending random data to TCP/135 killed WINS replication (or did it kill WINS totally?). Was that a false alarm? ---------------------------------------------------------------- Users Guide http://www.microsoft.com/sitebuilder/resource/mailfaq.asp contains important info including how to unsubscribe.
