Connect to computer on network, "save password" checkbox missing

[hkmission]

I am running Windows XP Media Center Edition, SP2, P4, 3Ghz, 1GB RAM, 80GB HD

I am set up on a network, using a network printer. The computer that the printer is connected to requires a password to login. When I go to view my workgroup, and double click on the computer that the printer is attached to, a dialog box pops up that prompts me to enter a user name and password. However, on the other computers on the network, it has a checkbox that gives me the option to save the password (ie, so every time I restart, I dont have to reconnect to this computer before I can print). However, here there is no checkbox.

Is there some kind of option that I need to enable in order to save connection information to other computers on my network?

Thanks in advance for your help!
