I have recently switched to Windows 7 Ultimate edition from XP Pro. The XP system worked fine using the old client. I have removed the old client file and installed the client for Windows Sp1 which according to the docs is the correct client for windows 7. Every thing looks as if it installs correctly but the windows 7 work station is unable to find the tree, much less log in. Also I do not see in the client property's any reference to IPX or SPX. Should they be there or do I have to change something on the server (5.1 for small business)??? The only change to the computer was software, XP to Windows 7
