Have you ever had experience about this issue?

then you can must check DNS name resolution and client PROXY configuration.
If those following statement ore true:
then your should check this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iphlpsvc\Parameters\ProxyMgr, if you can see any sub-Keys below ProxyMgr key then delete the whole ProxyMgr key and restart your DirectAccess client.
Status Connecting and Direct Access does working
Check your company DNS server zone for Directaccess-WebProbeHost.yourcompany.local entry and if it missing then create the entry with DirectAccess server internal IP (use VIP if you have NLB)
