DescriptionInternal error: Memory allocation failed. Check system memory resources.
Event Information According to Microsoft :

Cause :

This event is logged when memory allocation failed.

Resolution :

Correct memory allocation error

Memory allocation has failed in Password Synchronization. This can occur if the Windows Server operating system has insufficient virtual memory. Try closing some applications and programs that are not required and are using large amounts of virtual memory, and then restart Password Synchronization. If this fails to correct the problem, try restarting the computer.

If the problem persists, verify that the computer is not configured to use the maximum amount of virtual memory.

To solve this problem:
  1. Right-click My Computer and then click Properties .
  2. On the Advanced tab, in the Performance area, click Settings .
  3. On the Advanced tab of the Performance Options dialog box, in the Virtual Memory area, view the amount of virtual memory allocated on the machine.
  4. Click Change to view the maximum allowable virtual memory.
  5. If necessary, change allocated virtual memory to the size recommended in the Total paging file size for all drives area of the Virtual Memory dialog box.
  6. If you have changed the allotted virtual memory amount, click Set , and then click OK .
    Attempt to free virtual memory by closing unused applications, or closing all applications and restarting the server.
Verify :

Open the Services MMC and verify that Server for NIS is operational. If the Server for NIS service properties show that the service is not running, errors are preventing Server for NIS from operating normally.

To verify that Server for NIS is running
  1. Click Start , point to Administrative Tools , and then click Services .
  2. In the Results pane of the Services MMC, double-click Server for NIS .
  3. In the Service status area of the Server for NIS Properties dialog box, verify that the Server for NIS service shows as Started.
Use the ypcat command on a client computer in the domain on which the error was generated to verify that the Server for NIS service is available.

To use the ypcat command to verify Server for NIS service availability:
  1. On a client computer in the domain on which the error was generated, open a Windows Command Prompt with elevated privileges. To do this, right click Command Prompt on the Start menu, and then click Run as administrator .
  2. Type the following command, and then press Enter: ypcat -h NISServer- d Domain Mapname. NISServer represents the name of the server on which you want to verify that the Server for NIS Service is available. Domain represents the domain name on which you want to verify that the Server for NIS service is available. Mapname represents the name or nickname of a specific NIS map that the server on which you want to verify Server for NIS availability is expected to update.
  3. If you are prompted to provide the domain administrator account name and password, type the account name and password, and then press Enter .
  4. The ypcat Windows command-line utility prints the values of all keys from the NIS database specified by Mapname, which can be a map name or a map nickname. If the ypcat utility returns a list of key values for the maps you specified, the Server for NIS service is available.
