SCOM 2007 R2 and Windows 2008 R2 DNS Issues

Posted in SCOM, Work on September 10th, 2010 by Tom – Be the first to comment

Issue 1 – DNS 2008 External Resolution always in “critical” state
This is an issue with how the monitor performs the test. This link has a great explanation. I followed the instructions at the bottom and overrode the monitor to change the query from type NS to type A and everyone started working. Of course before doing this I spent half a day testing DNS on each server manually and trying to figure out what was going on.

Issue 2 – TrustAnchors
Another error the pops up is DNS 2008 Zone Resolution Monitor – TrustAnchors. This is constantly on alert status. This error is related in new functionality in Windows Server 2008 R2 for support of DNSSEC. This link has a great summary of the issue. Similar to this link, I just disabled this particular monitor as I am not using DNSSEC. You can disable it in Monitoring -> Microsoft Windows DNS Server -> Domain Health State View -> open the TrustAnchors Domain -> Go to Properties of the monitor and override it to set to Enabled = False.

Issue 3 – Cisco firewall throwing away some DNS packets
I didn’t actually run into this problem due to my configuration, but I easily could have. I found the issue as I was trying to investigate Issue 1 above. The issue is some external lookups can fail when DNS packets come in with a size larger then 512 bytes. This occurs from EDNS and DNSSEC. See this post for a better idea as well as the solution when using Cisco PIX/ASA firewalls.

WordPress on Windows – Automatic Upgrading

Posted in Technology on August 23rd, 2010 by Tom – Be the first to comment

I have never been able to get WordPress to automatically upgrade until today. Every time I tried it would ask for FTP credentials which no matter how I set up FTP it would always fail. I have tried this numerous times through the past year or two and finally I randomly found the solution via Google.

First the platform. Windows 2008 R2 Server running IIS.

Second the problem. Automatic Upgrade would prompt for FTP details, and even if FTP was setup for correct access to WordPress directories would still fail.

Third the root cause. WordPress directories had incorrect file permissions for the IIS to be able to access everything.

Finally the solution. I had incorrectly added the group IIS_IUSRS to have full permissions. What you need to do is add the user IUSR to have full permissions to the wordpress folders. As soon as I did that all the automagic worked like a charm.

I found the solution here.
