SYMPTOMS

You might receive the following error message during installation of Microsoft Exchange Server:
Microsoft Exchange Server Setup

Unable to configure the Windows NT Natural Language for the teletex codepage.

Access is denied. ID C0020005

CAUSE

This error message usually occurs because the System32\C_20261.nls file is marked read-only. It will also occur if the following registry entry is not present: 
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NLs
                     \20261:REG_SZ:C_20261.NLS

WORKAROUND

First, verify that Windows NT Service Pack 4 (SP4) has been installed. Then make sure that C_20261.nls is the file that came with SP4 and it is not marked read-only. Finally, make sure that the registry entry above is present.
