Assisted again Ms. Ira Salazar on her domain issue.  She can't still log in to her domain account/ I already ask assistance from Sir Ariel to reset her domain password then advise her to restart her pc. The same error is still persisting. Then we change it again to workgroup so she can login her account. but we still cannot install the NAV since one of the NAV requirements is to have a domain account registered on her pc. We tried again adding the domain and the problem is just repeating. I told them to check this first since this is a technical issue. I talked to Sir Mike De Villa regarding this and he said that this happened before and the Avasia did some changes regarding this. His tech support team fixed the issue. Since Avasia is no longer the support for LCI, they have the new third party support they also made some changes as per Sir Mike. So I advised them to check first on the issue regarding this and get back to me once they register the domain account of the user so I could install the NAV.
