Hi,

I need update my communication setting in sep client's (vr. 12.1.5), but the trick is, my last sysadmin change client password and i don't know.  I did a new fresh install of sep manager yesterday but the client's  i cannot update. Someone wa solved this?

Is the old SEPM still avaiable and is the clients still communicating to old SEPM ? 

If Yes - Just login to the SEPM and Change/Remove the client password and the deploy the communication update package

If no - You will have to reinstall the SEP client by performing a Cleanwipe and the a fresh isntallation of SEP client from the new SEPM

Does Old SEPM manager are available or not ?

How many sep client are available ?

If old sepm server not available with out password you can not communicate sep client.

If less sep client available you can solution available replace sylink.xml in safe mode .

Why do I need to replace the client-server communications file on the client computer?

Are you talking about apassword applied to stop SMC? If not, you don't need a password to replace the comms file.

Sorry, that's my problem

I have 150 clients

I deleted old sep and make a fresh install of sep manager

I don't have client password.

I try to deploy from new server but failure booth, client and comunication settings.

Have you tried exporting the sylink file and manually importing?

Also try to import sylink.xml in safe mode

Was the password set only to stop the client service or even to import a new policy file?

If you are not sure. try the following:

1) Open SEP client console on an affected PC

2) Go to Help -> Troubleshooting.

3) Click on "Import" under "Policy Profile". If it doesn't asks for a password that means you are good to import a policy that will disable the password on the SEP client, after which you can deploy the communication package without a password.

Please check the article at the below link to know how to export /import policies on SEP clients.
