I have a windows 2003 server that runs as a file server for some of our Macs and PCs. when the macs login, they get their shared mounted on their desktop and this has been working fine for about a year to a year and a half. suddenly this morning the 10.5 machines are asking the user to re authenticate to mount their share and requires that they enter domain\username, neither was the case previously. if you needed to authenticate to a share, you could just enter username and password. the 10.4 machines continue to function as they always had, it's only the 10.5 machines.
to the best of my knowledge, nothing has changed on the endpoints or the server, the server was rebooted last night, but there were no updates prior to that reboot.
has anyone come across this and found a solution?
