I install novell client 2 sp1 for win7 but my windows 7 ultimate can't connect to novell network server. please anyone help me..

I suggest you change the NTLM authentication level. Please refer the following website. Network security: LAN Manager authentication level The policy is: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network security: LAN Manager authentication level Please change “Send LM & NTLM - use NTLMv2 session security if negotiated”.Arthur Xie - MSFT
