Thanks - we are sorted. The TGT error still occurs but it logs in with the FQDN.
Hi, I have a Dell Poweredge R510 that is running Small Business Server 2011. SBS supports only a single NIC connected hence my NIC has one IP address for the server and a different IP for the IDRAC express card that is installed on the box on the same physical port. I am trying to set up the server for SSO and it is failing to resolve the DNS server (which is, of course, the Small Business Server) and hence 'behind' the shared NIC port. I cannot use the second NIC as that is not a supported configuration by MS.   Has anyone any ideas?   Thanks Mark
