I am using Cisco AnyConnect to connect to my work network for a work from home situation. The connection is fine, however I am having a DNS problem. My work DNS has various suffixes, but for some reason my Windows 7 computer simply ignores them when I add them to the "Append these DNS suffixes (in order)" option in network connection settings.
An example of my problem is this:
I am try to connect to example.foo
The full DNS entry for this entry is example.foo.bar.employer.com. This full address resolves perfectly. However, example.foo is not translating to the full version even though bar.employer.com is in my DNS suffix search list.
I have tried the suggestions in this question: Windows 7 not appending connection-specific DNS suffix
However, when I run gpedit.msc I do not have the options that are described in the answers. Specifically, I do not have "Allow DNS Suffix Appending to Unqualified Multi-Label Name Queries". I do have an option called "DNS Suffix Search List", although the description says this is for single-label name resolution.
A quick test shows that Windows is properly doing suffix searches with single-label look ups (example) vs multi-label look ups (example.foo).
Here is the output of my ipconfig /all:
