alerts are not working for my moss site. I tried a lot and I checked so many blogs and I don’t get the correct answer.

here is workaround

if you are getting below error try to specify server name instead of alternate aceess mapping url

for ex: http://contoso.com

try with http://moss1server/

http:moss2server

The server administration programs and the Windows SharePoint Services Web applications on this Web server are not compatible.  Ensure that the administration program is the same version as the Web application

check this command to check whether alerts are enabled for the web application

stsadm -o getproperty -pn alerts-enabled -url http://servername

enable alerts command

stsadm.exe -o setproperty -pn alerts-enabled -pv true  -url http://servername

command for run the job

stsadm.exe -o setproperty  -pn job-immediate-alerts -pv "every 5 minutes" -url http://servername

last step

services> timer service > start/restart  (or)

stsadm.exe -o execadmsvcjobs
