only open home page, i need to wait more than 5-10 sec.
there is nothing on home page, it's empty page .

any ideas will be appreciated.

you are facing default behaviour of IIS, which unloads web sites, after 20 minutes of inactivity. you may alter it by modifying app pool configuration or use a 3rd party tracking solution calling the home page every 15 minutes (e.g. www.host-tracker.com or mon.itor.us)

Well, it's not the big, technical answer that you probably want to hear, but --

I was having what I thought were the same problems and getting rid of AVG security did it for me. I went with MS Essentials and it works as expected.

I know it's probably anecdotal, but that's the problem i was having and that's what worked for *me*...
