ACS 4.2.1.15 RADIUS stops after a while

[Nikos Nicolaides]

Hi all,

We have 2 ACS 4.2.1 servers in Windows 2003 with SP2 installed. We have updated the first ACS to the latest patches for Windows. After that we started having problems. CSRadius either stops by itself or when some time passes we get the following error in Failed attempts "Unknown error". When we restart the ACS services by the GUI, it resumes until the next time it stops.

Do you happen to know if we have any bugs related to Windows patches?

Please set the log level detail to full under System Configuration -> Service Control and restart ACS services, then restart them one more time after CSRadius stops, collect a pacakge.cab file and review the RDS.log file, which you will find in the CSRadius\Logs directory

Hello,

Find attached the RDS.log

Note that when i asked my administrators, they said that we use Windows 2008 R2 Domain Controllers.

Known issue, due to the incompatibility between ACS 4.x and Windows 2008 R2. We do not have a fix for this, other than moving to ACS 5.x
