iCAP Computer and Laptop Communication Issues


FSEs use their laptop computers loaded with iTEVA of current or previous versions, to troubleshoot our customers computer and instrument communications issues. Firewall and virus protection, especially the Symantecs, are typically turned OFF.

With more current Windows Service Pack firewalls and anti-virus protection, turning these OFF does not turn off Auto Blocking to allow proper handshaking of iTEVA with the iCAP.

This has been observed with Symantec Client Firewall v8.7.4.104.
