While running InstallTool, the error message "Cannot generate SSPI context"
This is a MS-SQL issue that can be caused by improper authentication OR inability to resove the DB server name or IP. More information is in http://support.microsoft.com/kb/811889
In one situation, this was caused by a DNS error. DNS could not resolve the hostname for the DB server because there was not a DNS server that knew about the host.
- Add the DNS server
- Flush the DNS cache: ipconfig /flushdns
- Do nslookup by hostname and by address. SQL server will do a gethostbyname and gethostbyaddr when attempting to connect
- If you can successfully look up the DB server, then go ahead and continue with installtool.
