Testing SLP Availability


Hi all,

A quick one from me. Ever had site discovery issues on your client machine?

 

 You can stick one of the following into your web browser to confirm that the Server Locator Point is up and running:

 

 If you use AD Sites for boundaries

 

 http://<slp>/sms_slp/slp.dll?site&ad=<AD Site Name>

 

 If you use IP Subnets for boundaries

 

http://<slp>/sms_slp/slp.dll?site&ip=<Client Subnet ID>

 

 If you use IP ranges

 

http://<slp>/sms_slp/slp.dll?site&ir=<Client IP Address>

 

 Or if you use a combination you can concatenate the parameters

 

http://<slp>/sms_slp/slp.dll?site&ip=<Client Subnet ID>&ad=<AD Site Name>&ir=<Client IP Address>

 

So in my test environment if I run the following:

 

http://svr-cen/sms_slp/slp.dll?site&ip=192.168.10.0&ad=Default-First-Site-Name&ir=192.168.10.10

 

I get this response:

 

If I make my SLP unavailable, in this case disabling authentication: 

 

 Entering an invalid / undefined boundary

    Good work Rob.

    It would be worth noting that if a customer is using System Center Operations Manager then even if they are not using the Configuration Manager Management Packs then this would be a good synthetic transaction to setup in Ops Manager.

    Note that this does *NOT* work in SCCM 2012. If anyone finds a link that serves the same purpose in SCCM 2012, say something.
