Never seen this one before, and unfortunately it's happening here...lol.

Obviously it SHOULDN'T be showing MSHOME.NET at all, and the DNS server of 192.168.0.1 is incorrect, DHCP is supposed to set DNS to 10.10.10.41 and 42.
This just started happening this morning, and apparently is affecting most if not everyone.
I know from looking that mshome.net is the default for ICS, but obviously we are a company and aren't using ICS.
On the DHCP serverI'm getting:
event id 1202 for SCeCLI - Security policies were propagated with warning. 0x534 : No mapping between account names and security IDs was done.
event id 3000 in DNS log - the DNS server has encountered numerous run-time events. To determine the initial cause of these run-time events,
examine the DNS server event log entries that precede this event.
event id 4004 in DNS log - The DNS server was unable to complete directory service enumeration of zone .. This DNS server is configured to use
information obtained from Active Directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning
properly and repeat enumeration of the zone. The extended error debug information (which may be empty) is "". The event data contains the error.
WORKAROUND - If a client does an ipconfig /release and /renew then everything is back to normal.
Any help is very much appreciated...this is really odd...and I know management is going to want to know why it happened.
