ipv6 issue after vCenter DB migration

Hey all,

Having a weird issue after moving a vCenter DB from a dedicated SQL server, back to the vCenter Server with full blown SQL installed (Don't ask why!)

The migration has gone OK, but the vCenter service refuses to start as localhost is resolving to ::1 not 127.0.0.1. This appears to be a known issue as described in this article:

http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=2056296&sliceId=1&docTypeID=DT_KB_1_1&dialogID=137542957&stateId=1%200%20137554782

We've followed that to the letter and amended the hosts file and ensure that ipv6 is not selected on the network connection. Yet still when we ping localhost it resolves to ::1!! Any ideas how to stop this so we can get the vCenter Server service to start?

Thanks!
