In either WSS or MOSS, If you name a site prefixed with the word “com” following a single digit – for example com1,com2…com9 , SharePoint UI won’t throw a validation error, but upon browsing to the site , you will get the following nasty errors. Okay , why do I need to call a site prefixed with “com”? In our CRM product , we have this notion called “Communities”, self-standing collab sites which are derived from within CRM UI. While testing site provisioning code and the underlying site definition and for simplicity , we named the site “com1” and observed this behavior.
\n Action<\/strong>: Create a site collection or subsite and give it this title and url : com1 or com2 or com3………or com0.
\n Template<\/strong>: Whatever
\n Errors<\/strong>:”An unexpected error has occurred” [Screenshot<\/a>]
\n Or
\n “The resource cannot be found” [Screenshot<\/a>]
\n Or
\n A blank page is shown as default.aspx<\/p>\n

While trying com10 , we got “The page has encountered a critical error” once [Screenshot<\/a>] , but after doing IISRESET we never got that error message again. It was just a hiccup <\/a>\ud83d\ude42<\/p>\n

All the other sites named with com[Double digits] (com01~com09) seem to be working just fine.<\/p>\n

<\/a><\/p>\n

\"TwodigitsAreOkay\"<\/a><\/div>\n

\n It turned out that Com1 through com9 are kind of reserved words , referring to the serial ports. You can\u2019t create a file in the file system called com1 either.
