[AccessD] When it rains it pours!

I've been seeking help on an Access 97 DB that I've been working on, and I've finally made headway...got the security off of it, finally! Now I am trying to re-link the BE data. Well, guess what...I just got a call about another A97 DB...that I wrote 13 years ago. It has been working so good that their department depends on it now. Both of these have the same problem...re-linking. 
 
We've recently gone from a Novell network to Active Directory and I'm not sure how to use a non-dedicated drive for the link. I know what the link should be, but I don't know how to enter it...it seems to want me to "walk" out to it on the tree, but I'm unable to do this.
 
The Novell link was \\Nianet\.NEBNOV1_VOL1.CRTHSE.NC\DATA\ACCESS\DEPTNAME\PROGRAM.MDB ( file://\NianetNEBNOV1_VOL1.CRTHSE.NC.MDB ) and the AD should be...
\\10.11.218.10\nccfs01_data\DATA\ACCESS\DEPTNAME\PROGRAM.MDB ( file://\10.11.218.10_data.MDB )
 
...or...do I HAVE to map a drive letter?
