IIS log shows status 500 with GetVaultInformation.asp request: 

POST /EnterpriseVault/GetVaultInformation.aspx x=evoutlookext&evhost=https://ServerName/EVAnon 443 DomainName\user1 10.200.200.200 EnterpriseVaultOutlookExt-V10.0.2.1210 500 0 0 4734

Cause

Incorrect modifications to MDC file of Vault Cache on client computer.

Resolution

  1. Locate the client computer using the Source IP address logged in IIS logs for failed GetVaultInformation.asp call.
  2. On affected client computer, locate the MDC file under Vault Cache working directory.
    • For example, "c:\Users\username\AppData\Local\KVS\Enterprise Vault\"
  3. Verify if multiple MDC files exist with incorrect syntax.
    • For example:
    • C:\Users\tesuser\AppData\Local\KVS\Enterprise Vault\3529C584E021A44F97160CC84E7135D3\1C433161B09E74C4A9652209E23B73ACF1110000svr(1).mdc 09/26/2013 10:39 376120320
    • C:\Users\testuser\AppData\Local\KVS\Enterprise Vault\3529C584E021A44F97160CC84E7135D3\1C433161B09E74C4A9652209E23B73ACF1110000srv.mdc 09/26/2013 10:39 395166720
    • In this example, incorrect name of MDC is '1C433161B09E74C4A9652209E23B73ACF1110000srv (1).mdc'
  4. Rename MDC file to correct name.
