It depends on your OS

On Windows 7 etc its C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Config

On XP etc its C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Config

Hello,

To replace Sylink, follow the Steps

1. Click on Start
2. Click Run
3. Type smc -stop in the run field
4. Copy the sylink.xml file and paste under "C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\12.1.xx.xx\Data\Config" it will prompt do you want to replace the file click on Yes.
5. Start the smc service
6. Click Start
7. Click Run 
8. In the run field type the following command smc -start                                                 

To replace Sylink.xml file on computer you will have to use Sylinkdrop utility. You will find this utility by default at two locations

1. Every SEP client will have Sylinkdrop utility under bin folder e.g C:\Program files\Symantec \Symantec Endpoint Protection \12.1.xx.xx\Bin

2. You wil find it under tools folder with original setup files . (CD's or downloaded files)

3. Sylink replacer tool will not work with SEP 12.1

its in 

C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\12.1.xx.xx\Data\Config

I moved from one server to another and now some clients dont connect. The ones that dont connect are still configured to the old server. can I just copy the offline computers to a txt file and push the sylink to them?

In SEP 12 and the new sylinkdrop.exe tool can you set the sylink.xml location in a command switch so I could use psexec or something to run remotely against a list? This way I can avoid using the service stop and file replace method which strangely seemed to convert devices to user mode, or at least the console reported them in User mode even though the registry entries on the clients showed the preferred mode = 1.

Where can i suggest a feature? I want to be able to select a large number of user mode accounts and switch them to Computer mode vs. one at a time. I just dont have time to write SQL/VBScript/ASP in order to correct database data

     I have done this several times using a batch file converted to an EXE and then using hyena or some sort of remoteinstaller to deploy. I included an example of a batch.

you can also export and import sylink file from SEP manager console.

Go to clients tab then right click on the group to export the communication settingd
