I installed Win 7 Pro 32 bit, last week, I can't connect to the server...I'm seeing the drives on the server but every ttime I put the user name & password I'm getting aan error ... the other computers on the network can get access to the network...one has Win XP Pro and the other has Win Vista Ultimate. I got access to the network the first time I Ran Win 7... Please help...I'm getting access to the computers running XP Pro.. and Vista...Thanks Mawds55
