SYMPTOMS
When you start your Windows NT-based computer, you may receive the following error message:
CAUSE
This behavior may occur if the System subkey of the HKEY_LOCAL_MACHINE hive in the registry is too large to fit into the allocated memory space. Typically, this part of the registry is too large because services store a lot of information in their Parameters keys under the CurrentControlSet\Services key. The following services store large amounts of data under this key under certain conditions:
- Spooler (number of printers)
- DHCP (number of reservations)
- AT Scheduler (number of jobs)
- DFS (number of shares)
- Other and third-party services
WORKAROUND
To try to work around this problem, use an Emergency Repair Disk (ERD) or reinstall Windows NT. After you recover the computer from a backup or an ERD, you can either reduce the amount of data that a service stores or install the hotfix for the spooler service.
Windows NT Server or Workstation 4.0
To try to work around this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information about how to obtain the latest service pack, visit the following Microsoft Web site:

MORE INFORMATION
This issue may occur when something is writing too much data to the System subkey in the registry. The System subkey is designed only for information that is required to start the computer.
Intel and ARC (RISC) computers have a design limit such that 16 MB of memory is available at this stage of startup. The System registry file must share the 16 MB with the loader, kernel, HAL, and boot drivers. In some instances, the System subkey may be as large as 13 MB in size (or larger).
