If you downloaded and upgraded the Vault Server with Vault 3.5.2.5073 or Vault 3.5.2.5086, please note there is a possibility that two web.config files may have been left in your %TEMP% directory.
Please delete any vault* directories located in your %TEMP% directory.
This problem has been remedied in Vault 3.5.2.5087 as of April 21, 2007.
