2008 multi-homed dns server failing simple query but otherwise works fine

So my dns server was working fine, resolved queries, updated records, etc. But for some reason it kept failing the built in 'Simple Query' and 'Recursive Query' tests. After much messing around I discovered that it was trying to query the first interface it found. In this case it was the interface that I had manually excluded from the list because I didn't want DNS listening on it. I wound up changing the binding order for the network interfaces to fix the problem. After swapping them around I restarted DNS and voila the built in Monitoring started showing 'Pass' instead of 'Fail'. List of interfaces, notice the non-listening one shows up first. Under Network and Sharing, Advanced Properties, change the bind order. Restart DNS and try again.

SEP 11.0.6 disabled windows 7 firewall even though NTP was never installed

So I had to help another admin out with a fun issue this week. He had just upgraded his management server to Symantec Endpoint 11.0.6 MR1 and pushed out new clients. He created separate groups for laptops, desktops, etc and separated off the machines he didn't want to install Network Threat Protection on into their own group. The problem was that even though NTP wasn't being installed, it was still disabling the windows firewall (windows 7 in this case) and of course the new security center locked out the ability to reactivate it. The solution in this case was to turn Inheritence OFF for that group and then withdraw the Firewall policy from that group. After the policy updates it should release the old on Windows Firewall. I didn't have time to stick around for that so we forced the policy update from the client and rebooted the machines for good measure. 1. Uncheck 'Inherit policies and settings from parent Group xyz' 2. Click Tasks to the right of 'Firewall policy' and Withdraw the policy. Everything seems to work right afterward. Aside from the inconvenience of having a non-inherited policy to deal with later on when you want to make changes. In most cases I've found that NTP works a lot better than the older versions like 10.x had so you most likely won't ever need the contents of this post but just in case, have fun.

Installing Microsoft System Center Essentials 2010 without it failing

Okay, this was irritating. I started with a brand new fresh Windows 2008 x64 R2 install with all windows updates and the IIS and Application Roles installed. I popped in the DVD for SCE 2010 and rolled along and then it failed. Tried a few more times to no avail. After digging through the forums I found the answer. I had to uncheck the Microsoft Update checkbox! WTF MS? That of all things slipped through QC testing? Afterward it installed fine...
