0x81070201 error

Recently I was going through a critical issue. I used to gets 0x81070201 error when I open default page of my sharepoint site in WSS 3.0. While I was looking for solution one of the blogs gave me great relief. The issue may appear because Schema.xml files from site definition folder under sitetemplates on webserver or schema tag is missing from onet.xml. If you simply reload these files at site definition and listdefinition, your problem should be resolved. [While I was searching around for the similar issue, I observed that similar problem may occur if your schema.xml and/or onet.xml is not accessible] Thanks, Subhash
