NetLink SEHException in getDefaultLaunchString

Recently I have gotten this error a couple of times when running a
"compute" command through NetLink:

System.Exception: System.Runtime.InteropServices.SEHException:
External component has thrown an exception.
   at Wolfram.NETLink.Internal.NativeLink.getDefaultLaunchString()
 at Wolfram.NETLink.Internal.NativeLink..ctor(String cmdLine)
  at Wolfram.NETLink.MathKernel.Connect()
 at Wolfram.NETLink.MathKernel.Compute()
at Wolfram.NETLink.MathKernel.Compute(String input)

Restarting the machine fixes this, but it has come back at least once,
eventually, requiring another restart.  Any ideas about what would
cause this and how best to recover from it to avoid having to restart
the machine?
