Access Violation Error Message in Inetinfo.exe on Server with More Than 1 Gigabyte of RAM (263408)

The information in this article applies to:

Microsoft BackOffice Server 4.5
Microsoft BackOffice Small Business Server 4.5

This article was previously published under Q263408

SYMPTOMS

When you try to install BackOffice version 4.5 or BackOffice Small Business Server (SBS) version 4.5 on a computer with more than 1 gigabyte (GB) of random access memory (RAM), you may receive the following error message:

An application error has occurred and an application error log is being generated.
inetinfo.exe
Exception: access violation (0xc00000050),Address: <memory address>

CAUSE

The problem occurs during Microsoft Proxy Server Setup when Proxy Server attempts to restart the WWW services. Proxy Server Setup reserves a block of virtual memory that is based on the amount of physical random access memory (RAM) that is installed in the computer. When the amount of RAM is greater than 1 GB, the access violation error message is generated.

RESOLUTION

To resolve this problem, obtain and install Microsoft Proxy Server 2.0 Service Pack 1.

WORKAROUND

To work around this problem and install Proxy Server during BackOffice or BackOffice SBS Setup:

After you install Microsoft Windows NT Server, but before the installation of the BackOffice programs, add a MAXMEM statement to the Boot.ini file on the server to limit memory usage to less than 1 GB. For example:
multi(0)disk(0)rdisk(0)partition(1)\winnt=Windows NT /MAXMEM=512
After adding the MAXMEM statement, restart the computer.
Run BackOffice Setup to install the selected components including Internet Information Server 4.0 and Proxy Server 2.0.
Install Microsoft Proxy Server 2.0 Service Pack 1, but do not reboot.
Remove the MAXMEM statement from the Boot.ini file.
Restart the computer.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
