Hi
Client installed directly through RDP:
1. node-v12.18.0-x64.msi
2. iisnode-express-v0.2.21-x86.msi
Plesk panel application pool crashed and all other websites application pool also crashed.
Corrected by below steps and also installed Node.js using Plesk.
"C:\Program Files\iisnode" Deny permission for users psaadm_users,psaadm and psacln, changed to "read and execute".
"C:\Program Files (x86)\iisnode" Only read permission were found changed to Read and execute.
Note: permission changes from RDP not from DiskSecurity.xml though had entered same content mentioned in this KB.
Just want to know how this can be corrected as I have run Plesk reconfigurator for all possible option available.
how to add both location with correct permission.
