Hi Experts !
I have this SRM system where everything was fine till 2 days back.
Now; all of a sudden, SLDCHECK fails to launch the sld & gives the below message instead:
Landscape Directory server address missing (longtext)
Message no. LCR005
Diagnosis
The system cannot establish an HTTP connection to the Landscape Directory, because it does not recognize the corresponding server address.
Procedure
Check that a valid primary Landscape Directory server address is entered in the Exchange Infrastructure configuration.
SLDAPICUST, RZ70 & SAPSLDAPI all work great.
If I maintain the SLD details in Tcode LCRSERVADDR, SLDCHECK works...but since this Tcode should ideally stay empty, I don't wish to populate it....please help 
Thanks a ton !
