SUMMARY
Pagefiles are limited to 4,095 MB in size under Microsoft Windows NT 4.0.



MORE INFORMATION
Computers can hold large amounts of physical RAM, which has become more common. Up to 4 GB of RAM have been seen in installations of computers running Windows NT 4.0 Terminal Server and Windows NT 4.0 Enterprise Edition. These servers may require over 12 GB of pagefile space. Unfortunately there is a size limit of 4,095 MB on a single pagefile and only one pagefile is allowed for each logical partition.

For these large memory computers, the workaround is to divide up one or more large physical drives into 4 GB logical drives and use the entire logical drive as a pagefile. The administrator may create as many pagefiles as needed.

You can also reassign the drive letters to high values and use the following article to hide them from the users. For additional information, please see the following article in the Microsoft Knowledge Base:
