Some application is failing on the server. You try to logon on and the message below is shown:
The system cannot log you on due to the following error:
Not enough resources are available to complete this operation.
That happens because the kernel does not have the enough memory to load the operating system processes.
One of the possibilities is the “4GT” being active and forcing the Windows kernel memory limited up to 1GB. In this case you will find this line in the boot.ini file:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Windows Server 2003, Enterprise” /noexecute=optout /fastdetect /3GB /PAE
You may try to remove the “/3GB”:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Windows Server 2003, Enterprise” /noexecute=optout /fastdetect /PAE
Save the file and restart the server.
Pay attention. This may be a configuration required by the application installed on the server. Therefore you have to check if there are process that uses more than 2GB of memory.
