[Unattended] After install, ActivePerl error message

[coors . hn]

All,

I got Unattened to work ( after changing out NICs see earlier post) but after the install, at the first login a command window appears and produces this error:

Mapping \\ntinstall\install on Z:...
The command completed successfully.

...done.
The system cannot find the path specified.
The system cannot find the path specified.
Z:\packages\ActivePerl-5.8.4.810-MSWin32-x86.msi not found; press any key to retry.

I check my packages folder and there is nothing in there that says Active Perl.  Did I miss a step in upacking or did I not download somethign correctly?  I read through earlier posts which mention ActivePerl but I coundn't find one that seemed this same problem.  Is this critical.  It seems the OS is working fine (btw I am installing Server 2003)

Thanks
Heather
