Would IP scheme change of network cause issues with trust relationship on PCs communicating to the DC?
Posted on 2017-03-07
I have recently changed IP schemes of a rather good size network, taken from a class B "flat" network operating on the default vLANS to a network separated into more logical class C VLANS. In doing so we changed the IP scheme from 192.168.0.0 to a 10.1.x.x depending on the VLAN tag. This seemed to be the most logical/secure way to handle this. All these changes have been applied and operational for about three weeks now including all vlans handing out appropriate IPs based on VLAN tag. All this to say that the the default DC changed from 192.168.0.5 to 10.1.1.5
The issue was just brought to my attention that there were a few PCs that just recently appeared to have logged in the local user on a temporary account, which is not to big of deal other than the users had a few local docs saved, so they saw that these were not there. I am not working this issue directly and only getting update from someone on site. My question is would the IP change had any adverse affect on these machines seeming to have lost its "trust" relationship to the domain controller? Or is there another issue un-related?
Please let me know your thoughts...
