Net time + system error 53

On our network we have a Windows XP machine SP1. It's in the workgroup mdi on our microsoft windows network. It runs a dos program that requires that the date be set back to dec 12, 99. After this program is finished we have a script that is SUPPOSED to synchronize its date and time with our file server mathew who is on our netware or compatible network using the command net time \\mathew /set /yes. However, this produces system error 53 network path not found, despite working flawlessly for other machines on the same workgroup as her machine. You can type \\mathew in explorer and it resolves correctly, and all her drive mappings on mathew are intact. mathew is a netware machine and doesn't have an IP address, or I would've tried that. I've searched the internet for solutions, but to no avail.

COULD SOMEONE PLEASE HELP MEEEEEEEEEE!
