Wireless and wired GPO becoming unreliable

-

we have started having issues wired workstations , wireless laptops not seeing gpo changes or software installation gpos unless rebooted multiple times (more twice) , laptops booting login prompt before network connected , user getting "no domain controller contacted" errors unless wait several seconds , try again.

the workstations , laptops used connect wired , wireless networks , not connect after reboots unless add wait network , add other artificial delays in gpo settings add additional wait times.

this workaround makes reboot experience painful while users wait "applying computer settings" complete, if don't enable settings, network not available when login prompt displayed , software supposed installed during startup doesn't installed.

i think network issue , not workstation issue.  are there settings on  network switches should have our networking people configure way optimize quick connections when computers started or restarted don't have configure 60 seconds or more wait time on workstation side during reboots?

hi mygposts,

>>no domain controller contacted" errors unless wait several seconds , try again.

it seems clients didn't obtains ip address immediately.

if use dynamic obtain ip address dhcp server, use command: ipconfig/release & ipconfig /renew to renew ip address dhcp server test issue.

best regards,
