.net application has a device attached to the system is not functioning

This is an occasional random error from my 32bit .net application when it connects to sql server.

System.ApplicationException: A device attached to the system is not functioning. (Exception from HRESULT: 0x8007001F)

The System.Threading.TimerBase.AddTimerNative() method is an internal call, see Microsoft source code.

I found another link on the web that discussed about CLR Does CLR internally spawns a thread to respond to timer events?

Since I don't know how AddTimerNative is implemented, I don't know the cause of work around this error.
