Network Logon Problem to Win2000P WkStat

I cannot logon to my “Workstation” from my main computer named “Server.” Both have the same workgroup & using same protocol, but the Server is Win98se & Workstation is Win2000 Pro. I have no problem accessing the Server from the Workstation, but when I try to access the Workstation, I get a prompt asking me for the password to make connection, even though I have the folders shared on the Workstation without passwords. The prompt resource path is \\WORKSTATION\IPC$ which is not the path to my shared folders. I have read tons of material and even bought several of your books and other Windows 2000 books, but none have answered this problem. Any help would be appreciated. Thanks.
