can’t access network resources on Win Me

My PC is runing Windows XP and try to access the network resources such as files,printer sharing from the PC which is running Windows Me but it would allow me to access and showing message “The account is not authorised to log in from this workstation.What is actually happen???,but other PCs which is running Windows 98 can access the network resources,is it need to set rights or something??
I would appreciate if anyone can help me to solve this problem.
thanks
