Very strange that Resco doesn't work.

(From Resco's FAQ website section):

"
8. Network drives mapping
Q. I can see no "Computers Near Me" in the Network Drive Mapping window.
A: Please check the IP subnets in the Settings dialog. The desktop PC and the PDA must use the same subnet and this subnet must be listed in the settings. Use the Autodetect feature which enumerates all PDA's network adapters and collects all active subnets for scanning.

If your network structure is a complicated one and the auto-detect feature does not work, please turn it off and manually specify the subnets which have to be scanned.
"

What version do you have?

Maybe a re-install?

(It can't be any simpler, with its auto-detect network search)
