I have an issue with RDS access on ONE network only (assuming 10.10.0.0/24) It give me "crendetials didn't work" message just after log in.

RDS access is ok all other networks (10.10.3.0/24 and 10.40.0.0 for example). When i connect to server 10.10.0.16 from VMWare Console, i can RDS other servers in 10.10.0.0/24. NLA is activated for ALL networks.

My client is 10.0.4.101 but when i trie to connect from 10.40.0.11 to 10.10.0.16, same error "crendetials didn't work"

On wireshark :

on event viewer :

id event 143, socket TCP error 64
id event 226 error code 0x80070040
id event 103 reason 4407

what i ve done :

sfc /scannow >> no errors
dism check/scan/restore health >> no errors
netsh interface ipv4 set subinterface "Ethernet0" mtu=1452 store=persistent >> no change
deleted rds selfsigned certificate
restarted rds services
Test-NetConnection -ComputerName 10.10.0.16 -CommonTCPPort "RDP" -InformationLevel "Detailed" >> all ok
GPOs to disable ModuleRemoteFX.
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\ DWORD: MaxOutstandingConnections VALUE: 10000

And still no luck. Any advice?

EDIT :

As local admin, i can connect.
I also can connect when i m on 10.10.4.0 network.

EDIT2 and 3 :

unjoin and rejoin domain: OK >> but after another reboot KO.

Thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
