I have USR Radius 5.5.3 authenticating my Hyper chassis. Quite frequently of late all 3 on my NT authentication servers will crash at the same time with the following error: The instruction at "0x77f6cde6" referenced memory at "0x00000010". The memory could not be "written". - Click OK The event log shows the following 3 entries: Error in security socket create 10048 [C:\5_5_3\project\5_5_3\RADNT\src\Ccomms.cpp(401)] No data for: SYSTEM.NW_SERVER [C:\5_5_3\project\5_5_3\RADNT\src\RADSERV.CPP(649)] No data for: SYSTEM.TACACS_SERVER [C:\5_5_3\project\5_5_3\RADNT\src\RADSERV.CPP(649)] Any Ideas? Can somebody purposely send a string to be authenticated that Radius can't handle? Would 3Com's new Radius solve the problem? Does anybody recomend a third party Radius?
