I have a small issue, I have a streamed IE from a RDS farm with 2012r2 up to date and SEP (Symantec endpoint protection). We use also view 7.01 connection server and view agent. My issue is when we open a link in a new tab. IE is freeze for one minute until the next tab is opened in a new window. Of course if a have a full desktop session on IE farm no problems, only when is streamed. I couldn't find any errors in view or windows.
Had exact same issue and problem was 7.01 agent in RDS. After upgrade to 7.1 and all my streamed IE issues were solved.
In logging of the RDS you also see DCOM error when opening tab for IE when running 7.01.
Usure if 7.02 or 7.03 fixes this but 7.1 does.
