Starting with Version 12, we are getting the following errors on two of our servers. I've rebooted the servers (and PRTG servers) and it doesn't seem to help. One of the servers is a Windows 2008 box and the other is a Windows 2003 box.
PRTG 12 may not have caused the issue, but after the install, these two servers have multiple sensors with this error. I just upgraded to the newest build (1881) and it displays the same behavior.
Do you have any suggestions?
