My domain credentials are OurDomain\Bob with password *******.
I have two computers that are attached to sane 24 port switch.
On BobsComputer my credentials work fine when I double click on a shortcut to \\DomainServer\share\Destination.
On OddballComputer the same credentials do not work.
I can get around the problem by using Remote Web Access. I find the RWA interface is a little clunky, but OddballComputer can get to \\DomainServer\share\Destination. (original post had a typo. I have underlined the correct computer name)
------------- more details --------------------
There is one painful detail that might explain everything:
Our network has 12 computers and OddballComputer is only one that has not joined the domain. It is a windows 7 WORKSTATION computer with static ip 192.168.16.99.
Oddball has a legacy application that runs twice a month. It crashes easily so I don't make unnecessary changes, and will never join it to the domain.
Twice a month I sit down at Oddball and run the special application which puts a text file onto Oddball desktop.
Aftwerwards, I double click the shortcut then copy the text file to Destination.
This used to work but about 3 months ago Windows 7 stopped accepting the OurDomain credentials.
Does anybody have any suggestions?
