My network skills are poor so bear with me! Have recently built an XP client (no service pack). When trying to join domain I enter account details and it just sits there? Have checked the NIC - seems fine, have checked the DNS settings - seem fine. Have checked cables - seem fine. Am able to ping AD server from troubled client fine by name and ip and can also do nslookup of the AD server, however if i try the reverse from the AD server it resolves with an address/ip of a different client on the network. Seems that the troubled client has picked up the ip of an existing machine which again is odd as it hasnt complained about 2 clients conflicting. Have tried releasing address of the troubled client but it just picks up the same one again - I guess a good test would be static ip but as I need to use dhcp im at a loss as to why this is happening at all Can anyone please help me....? Many thanks!
