PC can connect to others on LAN, but not vice versa

I have 5 WIN2K pcs on my LAN (Linksys router, static IPs). They can all see and share with each other EXCEPT ONE - mine. Mine can connect to the other 4, but if I try to connect to mine from any of the other four, it prompts me to "Enter Network Password." I don't have any of my pcs setup to require a password at bootup, none require a password to logon, and none have a password assigned. Furthermore, they all are setup with the administrator as the default single user (I know, I know, but that's another story. I am behind a router and a firewall. Am I safe?)

Anyway, if I try to connect as administrator, it says "Incorrect password or unknown username"

What am I overlooking here?

Thanks,
Scott

 

Log to this page it has a lot of links to instructions to Windows Network Settings, and Sharing.

Link to: Windows Network - Installing & Sharing.

 

Thanks for replying. I don't believe that addresses my problem. Remember, when I click on Network Neighborhood from another pc on my LAN, I can see my pc, but I cannot get into it. I can get into the other pcs (and they can get into each other) without any shares set up (using the $ administrative share). Furthermore, I am perplexed by the login querry and the fact that it won't accept my login as administrator (or any of the login/pws I may have used in the past).

Someone out there must have come across this specific problem before.

Thanks,
Scott

 

Ive not had this problem exactly but have you checked under the sharing of folders or drives that they do not require a password for some reason, it is possible that its some obsecure default on your machine?
