Cognos Metrics List ‘Server Error in Application’ (Duplication Error) on MOSS 2007

If you receive the following error regarding a Cognos Webpart in MOSS 2007 be sure that you have the credentials correctly specified for the namespace:

Duplication Error

Type=HtmlAttrribute, Begin=584, End=587, Name=DTD, Value=””


You will need to delete this page by going into the web parts maintenance page (?contents=1 ) and closing or deleting the webpart and then will need to change the credentials defined for the namespace



As it turns out this could be related to authentication for the namespace (I also assume it relates to other types of errors)
