Hello Ibrahim,
the question may be related on some initial multicast discovery attempt made by RDP client.
multicast or broadcast traffic is not encrypted and your ACLs specify local or remote IP subnets.
IPSec works well with unicast traffic.
the usage of WINS servers or the usage of ip helper address command may help in your case.
Verify also the MTU on the encrypted path you need to be able to support packets of 1500 bytes end-to-end between client vlans.
Hope to help

It is not possible to support MTU of 1500 on IPsec circuits, due to encryption overhad.
However, that should not pose any problem on an otherwise correctly configured network.
