first of all . setup initially worked awesome hardware was
I7 4770k
8GB ram
gigabyte H97HD3 motherboard
Intel I350 t4
server 2016 std
then motherboard burned .. and we changed it . as well as full windows reinstall . new configuration is
I5 7500
Asus Q270M-c
8gb ram
Intel I350 t4 ( same card )
server 2016 std
server intended to perform as VPN+NAT for RRAs . and as file share .all worked fine with previous board . with new one . separately it works
RRAs works fine in any setup . no question there
SMB works ONLY with rras disabled . if i enable rras even with smallest possible variant ( generic NAT ) . SMD stops working after 2-3 min . after 2-3 min i can read contents of smb share . but could not write or read ( technically i can . but speed of that is so low . so explorer freeze .does not matter rras settings . even vanilla variant ( generic nat ) freeze smb .
1. smb version is 3.1 used
2. no load on cpu or ram while it hanged itself
3. if access share after drives spinned down ( sata link power management ) .disks immediately spins up . but no read/ write is made
4. rest of setting is default ..previous installation was with same settimgs and from same media .. but it worked !
runned out of ideas where try dig i
5. does not matter how configured RRAS . even vanilla RRAS ( NAT only ) WITHOUT ANY interfaces . render SMB non working .
6. strange things on client side
PS C:\Users\ADM> test-netconnection SRV-01 -CommonTCPPort SMB
