This article lists down the steps that help clear the cached domain values in TDV Studio. 

Note: The Studio GUI memory changes are dependent on the windows user profile under C:\Windows\users\<user>\compositesw\studio.properties file. 
 

(1) On the Windows machine where the TDV Studio is installed, close all the open Studios.
(2) Navigate to the location C:\Windows\users\<user>\compositesw\studio.properties on that machine
(3) Open the file studio.properties in an editor
(4) Search for the word 'domain' in this document. 
------
Example: 
domain=composite,LDAP_US,test_AD
------
(5) Remove the values that are no longer needed.
------
Example: 
domain=composite,LDAP_US
------
(6) Save the file
(7) Open Studio and check the domain values.

Note: The above steps are to be followed on every machine that has a TDV Studio installed as these values are TDV Studio specific and not the TDV Server.
