Vista - WLan Service Will Not Start

The wireless capabilities of my Vista laptop recently stopped working and
after some investigation I found that the WLan service was not running.
After several failed attempts at starting it, I went looking for more
information and found the following int he Event log:

"The WLAN AutoConfig service terminated with the following error:
WLAN AutoConfig is not a valid Win32 application."

I also got the following detail at the command line:

C:\Windows\system32>sc query Wlansvc

SERVICE_NAME: Wlansvc
TYPE : 20 WIN32_SHARE_PROCESS
STATE : 1 STOPPED
WIN32_EXIT_CODE : 193 (0xc1)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0

Anyone have any ideas what may be going on here? Are there additional logs
I can look at? Perhaps some file permissions I can check? I attempted going
back to a previous restore point but it looks like the earliest one available
to me has this same problem.

Suggestions?
