PSEXEC - "The Handle is invalid" When running the command as System User

Psexec forces to use System user account by adding -s parameter.

We use psexec to launch some task in remote computers and it logs in a database table. When we dont use -s parameter user appears as domain\administrator but if you use -s parameter it appears as "System"

For the invalid handle message check this:

After much research, it is a windows security feature to block all network access to the system user, which includes running tasks as another user. The best method I have found to circumvent this , is to create a scheduled task to run psexec from an administrator account.
