Using MS Internet Explorer to access the Nerve Center, upon logon, it is possible to get the error: “Cookies not enabled in your browser, Nerve Centre requires session cookies to be enabled" when in fact the browser is set to receive cookies. NOTE: Mozzila Firefox will not show this error. The problem may be due to an illegal character in the Server network name (e.g. underscore).
Solution 1:
Access the Nerve center using server's IP instead of the server name.
Example: http://192.168.2.226/signup
Solution 2:
Rename the server, removing the illegal characters
Update the SQL database.
exec sp_dropserver[oldname]
exec sp_addserver[newname], LOCAL
Edit registry keys.
Run regedit and open HKEY_LOCAL_MACHINE\SOFTWARE\Pharos
and change the server details to the new name.
