Mapping a network drive without hardcoding a drive letter in a batch file

Question

I need to map a network drive with a batch file, but don\'t want to specify the drive letter.

The batch file is used as part of a deployment process; I call the batc

Answer 1

Ok... this might not be glamourous but this is how I'm doing this now; a basic try catch approach. Try to map a drive and if it's in use then goto the next step. I've illustrated this with just 2 attempts, but it's not hard to extend it to 4, 10 or more drive letters.

Yes it does offend my programming sensibilities, I don't like the repetion of code. Unfortunately I don't know how I could pass the path and credentials into the batch file as I don't call it myself, CruiseControl.net calls it without parameters.
