I am attempting to connect to shared drives on my main desktop over my LAN from my laptop. Same problem when using another desktop.
When I enter my desktop username (has admin rights) and password it just reprompts me repeatedly.
My main desktop is running XP Pro SP3, the other PCs are running XP Pro SP2.
I have no problem accessing the Internet (via the LAN) from the laptop.
I do have a firewall (Online Armor v.3) installed and I am using windows firewall.
I have tried switching off Online Armor v.3, but it makes no difference.
I have enabled file sharing in folder options, also Everyone has Full Permissions.
I've checked both computer for some sort of security error to see if the problem is authentication related but there appears to be no logs on either computer.
I have looked at the Windows Firewall log (C:\WINDOWS\pfirewall.log) on the primary desktop (IP=192.168.1.99). The only entries relating to the laptop (IP=192.168.1.254) are of the form:
2009-02-16 17:00:11 OPEN-INBOUND TCP 192.168.1.254 192.168.1.99 1378 80 - - - - - - - - -
