Net Use – Anyone ever seen this vodoo.

I have a share that for the life of me will not map to a drive letter. Here is what is being done.

NET USE T: \\ensler_ho3\transfer

All other net use commands in the script work except this one. When the login script runs I get this message.
System error 53: Network path not found
for more information type: net helpmsg 2250 at prompt.

(This share has been moved to 3 different servers. Same error message every time.

After login if I go to a command shell and type NET USE T: \\ensler_ho3\transfer IT WORKS!

Any ideas, tricks, or solutions greatly appreciated.
