Body
We have a hybrid WCF and ASMX web service currently being used on a decent sized project. Now, most of time everything works perfectly fine, however on rare occasions and seemingly randomly, the web service begins to block calls which returns a 401 Unauthorized error back to the page in question. It seems to be the ASMX service calls that are causing this, but given that's it doesn't occur often and isn't reproducible I can't say this for certain. The error goes away after an IIS reset, and at least on one occasion it eventually just went away on it's own. We use Windows Authentication as the credential type with anonymous access disabled. Anyone have any ideas about why this might be occuring?

1. COI have encountered this when the response was longer than a certain size (some megabytes) and the authentication was also Windows Authentication.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
