Checked the concern reported by Ms. Lorena Manalang, she advised that the NAV has been working properly without being disconnected, however, one of their staff is processing from sales journal and takes a long time to post. Checked the ping status of the machine. Validated if the user tried to post from other machine, she said that she tried and its loading only as well. Validated with Ms. Jen from SSI if they are experiencing the same issue. I advised that I will restart the NAV after EOB they they agreed that they will try to post again from the sales journal after restarting the NAV.
