Either a login script command or I have used a script that writes a scheduled task (for immediate run) on the remote system for a similar client task.If you know anything about scripting WMI, you can zap the lease renewal time on any workstation by changing the value of the DHCPLeaseExpires property on the relevant Win32_NetworkAdapterConfiguration. Put that in a login script.Few things to chew on, there.Neil :) + 0 Votes option 3 router and CG IT 6 years ago as neilb said use a script to force a ipconfig/renew. option 3 router designates routers on the subnet, in your case, your gateway router. see RFC 1497 basic DHCP options. + 0 Votes . maximos2111 5 years ago . + 0 Votes . maximos2111 5 years ago .
