test-connection returns invalid query error
in many of scripts loop through array of computer names, use "test-connection" first make sure computer alive before moving on script. sometimes, period of several minutes, test-connection cmdlet stops working try - whether run script or manually run ps command prompt. example:
test-connection "servername"
"invalid query error"....
i tried using fqdn, , providing argument in command line of computername:
test-connection -computername "servername"
the after several minutes, randomly starts working again - dont close ps window or logout of server console - starts working again same ps command window session. running on windows 2008 r2 sp1 standard, ps 2.0.
anyone else seen this?
