I have a 2003 sp1 fully patched server.\nI have two interfaces\nthe server has a hostname=server1 (type hostname at a prompt)\nthe server has a FQDN of server1.mydomain.com with IP address 184.108.40.206\nin addition it has a secondary IP address on that server whos FQDN is\nserver2.mydomain.com with IP address 220.127.116.11\n\nping server1 = works\nnet view \\server1 = works\nnet view \\18.104.22.168 = works\n\nping server2 = works\nnet view \\server2 = "System error 5 has occurred. Access is denied."\n(I am logged on as admin on the box that has the ip address)\nnet view \\server2.mydomain.com = fails\nnet use * \\server2.mydomain.com = fails (I get prompted for the username\nand then System error 1326 has occurred.)\nnet view \\22.214.171.124 = works\nnet use * \\126.96.36.199 =works\n\nnslookup server2.mydomain.com\nreturns 188.8.131.52\n\nWhy does this happen? Any time the FQDN does not match the HOSTNAME then\nNET XXX failes.\n\n\nThanks in advance. links to support info helpful.
