Invalid Domain Name Error Setting Trusts in Different Languages

• Microsoft Windows 2000 Advanced Server
• Microsoft Windows 2000 Professional
• Microsoft Windows 2000 Datacenter Server
• Microsoft Windows NT Server version 4.0

SYMPTOMS

When you try to use the Active Directory Domains and Trusts MMC snap-in to establish the trust between two domains, the Trust may not be established, and you may receive the following error message:

Invalid Domain Name
The operation is disallowed

CAUSE

This issue can occur if the DNS names for the two different domains are not using the same language. For example, this could occur if domain A's name is MYDOMAIN.MYGROUP.MICROSOFT.COM, and domain B's name is foreign language name.MYGROUP.MICROSOFT.COM, where foreign language name is non-English characters.

MORE INFORMATION

In order for the domain trust links to be established, both domains must use the same Original Equipment Manufacturer (OEM) code pages.

The ANSI (American National Standards Institute) character set maps the letters and numerals in the same manner as ASCII. However, ANSI does not support control characters and it maps many symbols, including accented letters, that are not mapped in standard ASCII. All Windows fonts are defined in the ANSI character set.

An OEM (original equipment manufacturer) code page is built into the computer hardware. There are a number of OEM code pages, each defined for a particular language. These code pages are referred to by a number, for example, code page 437 represents English, while code page 863 represents French Canadian, and code page 850 represents SQL Multilingual.

Code pages also determine the character correspondence tables used to set up foreign language versions of software, and also indicate how a utility should map various extended characters that can appear in usernames, account descriptions, and so on.
