After installing Encryption Desktop, internet or network connectivity is lost.
Encryption Desktop 10.3 and above.
Encryption Desktop can encrypt SMTP, POP3 and IMAP email automatically and without the use of any plug-ins in the mail client. In order to do this, Encryption Desktop utilizes a level of the operating system that deals with Internet/network connectivity called the network stack or Layered Service Provider.
From a high-level perspective, Encryption Desktop utilizes the network stack in order to proxy the connection for email or AIM and is therefore able to encrypt the email. At the user level, the network stack is the level of the operating system that allows applications to communicate with network or Internet-related services. These service may include communication with an email client to send/receive email from an ISP.
Many third-party programs use the network stack in order to perform network functions. For example:
Because Encryption Desktop utilizes the network stack and other third-party programs do the same, sometimes conflicts can arise and connectivity can be lost with the programs and, in some rare cases, lost altogether.
Encryption Desktop creates a registry file that will roll back the network stack to its original state prior to installation, restoring any connectivity that might have been lost.
If you do not need to encrypt POP/IMAP email automatically with Encryption Desktop Email encryption, you can run this registry file to restore connectivity.
Alternatively, you can upgrade to a newer release of Encryption Desktop and disable LSP by passing a parameter to the msiexec command. Please see article TECH249430 for further information.
Using the PGPlsprollback.reg file
Locate the file in C:\Windows\System32 or C:\Windows\SysWOW64.
Double-click on the file and click Yes to merge the information into the registry. You will need administrator permissions.
Reboot the machine. If Encryption Desktop was causing any connectivity issues, this should solve the issue.
If in the future you need to use Encryption Desktop for SMTP, POP or IMAP, you will need to reinstall Encryption Desktop.
Note: This disables email encryption only for SMTP, POP and IMAP. Symantec Encryption Desktop encrypts MAPI or Lotus Notes email in a different way and does not disable these services for email encryption.
The File Share encryption feature can also cause some rare connectivity issues. If this is the case and File Share encryption is not required, unregistering PGPfsshl.dll may solve these issues. For more information on how to unregister this driver, see article TECH149076.
