Hi All
We have faced a strange issue lately with some Windows Servers.
(Mix of Server 2003, 2008 and 2008 Core - Physical and Virtual (Hyper-V))
Their Gateway IP has changed or the Subnet mask has changed causing loss of connection.
Example: Gateway changed from 10.1.12.65 to 10.1.12.1
Example : Subnet Mask changed from 255.255.255.224 to 255.255.255.0
We've been unable to track these changes, as there isn't anything logged in the event viewer.
Has anyone heard of something similar happening?
Have run AV scans on the servers and not been notified of something malicious.
