Thanks mkline for your response, if we limit the number of RPC dynamic ports on each DC for say 100 ports, will the clients in this case able to authenticate or not?

Dear,<br />
I am having all the DC's and exchange are in the same VLAN, and I need to customize the number of dynamic ports on the DC's for internal firewall<br />
When I issue the below commands:<br />
netsh int ipv4 set dynamicport tcp start=49152 num=1000 &nbsp;<br />
netsh int ipv4 set dynamicport udp start=49152 num=1000<br />
&nbsp; I am having a problem that the DNS service is stopped, and it will work after starting the service manually.<br />
&nbsp; Is there any reason for this?<br />
&nbsp;and is there any impact for limiting the number of dynamic ports in the DC?<br />
&nbsp; Thanks

Dear,
I am having all the DC's and exchange are in the same VLAN, and I need to customize the number of dynamic ports on the DC's for internal firewall
When I issue the below commands:
netsh int ipv4 set dynamicport tcp start=49152 num=1000  
netsh int ipv4 set dynamicport udp start=49152 num=1000
  I am having a problem that the DNS service is stopped, and it will work after starting the service manually.
  Is there any reason for this?
 and is there any impact for limiting the number of dynamic ports in the DC?
