SYMPTOMS
If an Internet News Server (INS) slave receives a replication request (XREPLIC) for a newsgroup that contains an illegal character at the start of a name component or an illegal word as a component of the name, you receive the following error message:

501 Syntax error

This causes the UNIX news package InterNetNews (INN) to disconnect, and leads to blockage of the newsfeed.



CAUSE
The INS does not allow a newsgroup to be created with the plus sign, the minus sign, or the underscore character at the start of a name. This is also the case when trying to create newsgroup names under the INS properties page.

Additionally, INN allows the word "all," which cause INS to send the "501 syntax error" message and ultimately causes the feed to drop. The word "all" is the only specifically referenced illegal name. See the RFC (Request For Comments) at ftp://ds.internic.net/rfc/rfc1036.txt. The following is an example of an illegal group name because it contains the word "all" as a name component:

alt.gamera.is.friend.to.all.children



STATUS
Microsoft has confirmed this to be a problem in Microsoft Commercial Internet System version 1.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Commercial Internet System version 1.0.
