We have one user out of our entire organization that gets the attached pop-up message when she opens Outlook. She is able to simply click "OK" and all can use her email just like everyone else, but this pop-up continues to occur. It has happened for years apparently and doesn't matter what computer or version of Office is installed, the pop-up remains.

We have tried doing everything possible troubleshooting locally but the simple fact that it appears on multiple computers rules that out as a solution. We have a hybrid setup for Office 365 and nobody out of our 500 users receive this message outside of herself. We believe the issue is somewhere on the administrator side of Exchange/Office 365 but we are unsure where since everyone isn't affected. Our next step is to call Microsoft but wanted to try Experts Exchange as a last resort.

Can someone get me started on the troubleshooting?  What is happening and how can I fix?
So I have a client with a couple of Apple MAc's for the design team. They have two identical HP CP5520 Colour LaserJets, even built in the same month, same firmware, etc. One of the Mac's can print to one of them and not the other. Just hangs at "Printing - Connected to Printer" until eventually it pauses the printer. I have tried both via "Secure AirPrint" and the other driver listed which I assume is Jet Direct. Both methods work fine with the other printer.

I have compared every web manage page and cannot see any differences other than, and this sounds completely irrelevant, in the General Troubleshooting page, one of the pages auto-hides the options for the paper path test, and the other doesn't.

Very confused. Off to find out how to turn the CUPS web interface on to see if that tells me anything.
On my Windows 10 homer system my Quark XPress 2017 is crashing on launch and I am not sure where the logs are located to start troubleshooting. Can you point me to the logs location?
Windows 10 Pro - Windows Update error 0x8e5e0147 consistently failed. This is for feature update on KB4462919.  Microsoft clues also fail.   Standard troubleshooting goes through the iterations all to no avail.  DISM and sfc /scannow completed, but continues to fail.  None if these routines appear to resolve the issue.  I've uninstalled all unnecessary apps and have plenty of storage and memory.

Don't want to do any Windows reinstall processes, too many old apps needed that I can't reinstall.  Not urgent, but perplexing for a couple of weeks.  Any ideas?

NEC SL2100 phone system started behaving poorly a week ago Sunday.  Rebooted all network equipment, and nothing changed.  Reboot the phone system and everything worked for about 20 minutes.  Same cycle of events, about same time frame.  Next checked all network equipment for firmware upgrades.  Wireless bridge Engenius EnStationAC went from 2.x to on both sides successfully.  Problem returned yet again, but now a delay in getting dial tone of about 3-10 seconds.  If phone hangs up and connects immediately, no delay happens.  A monitoring computer is the only non-phone device on the entire voice network.  It shows random packet loss to phones.  The phone problem was originally they begain restarting at random.  They are not all happening at one time.  The delay never happens to VOIP phone on the system side of wireless bridge.  Engenius has yet to comment on the issue.  One phone (Only one phone) peforms IGMP actions accoring to Wire Shark.  Removing that specific phone solved the problem for almost 2 hours.  Yet it eventually returned.  All the time I have brought another laptop in for testing and moving it to both sides of the bridge.  If I am on the system side, I perform ping tests to the phones on the far side of bridge.  If I am testing the phone system resources, I am on the opposite side of bridge.  I perform around 1,500 packets to 3 devices simultaneously each time I test.  No latency or packet loss ever.  I have introduced a new PoE switch on the system …

Hi guys

I'm working on putting together a technical test to help a colleague in another country in their recruiting process. The candidate claims to have had 9+ years working in Microsoft environment based system administration, maintenance, troubleshooting and support of data centers. This in itself is rather vague. They do claim to have had Level 1, 2 and 3 support in a Windows server environment during the 7years of their tenure.

I've got around 15-20 questions set up already. I was going to ask if it was possible for some of you to throw some technical questions around Active Directory, DNS, DHCP and SAN's. I know this isn't specific to any particular topic which makes it harder. But if you can think of any questions that I could perhaps ask them, then I'll review it. Any help would be great.

Thanks for helping
Hello Experts,

One of my customers is running into an issue where they are unable to mount a mailbox in Exchange 2016 that was disabled by mistake and then reconnected to another user in AD.


Mary Doe's mailbox was disabled for some reason, and the help desk team, instead of reconnecting the disabled mailbox, they provisioned a new mailbox for this user. Once the user check the emails, obviously all email is gone because is displaying only items from this new mailbox.

Company has a test account named John Doe with a mailbox. The mailbox for John's account was disabled, and then following cmdlet was performed to reconnect Mary's original disabled mailbox to John's mailbox

Connect-Mailbox -Identity "Mary Doe" -Database DB100 -User "John Doe"

And the following error was displayed:

The LegacyDN xxxxx is in use by the following user in Active directory: Mary Doe. The value for LegacyD must be unique to each user.

In order to resolve the issue above, they added an extra blank space to LegacyDN attribute in AD for Mary Doe using ADSI edit tool, then ran cmdlet below, and Mary's disabled mailbox was successfully reconnected to John's account

Connect-Mailbox -Identity "Mary Doe" -Database DB100 -User "John Doe" -AllowLegacyDNMismatch

So, we also granted full mailbox permission access to Mary's and John accounts to perform troubleshooting, however we are unable to mount or open Mary's mailbox from John's account using outlook and OWA. Getting …

My client has an HP ProLiant DL160 Gen9 that has started rebooting randomly over the last two weeks, below is the latest bluescreenview which points to ntoskrnl.exe as the culprit however i have no idea where to start troubleshooting.

All applicable windows server updates installed and i also ran a system file check which did resolve some issues however the reboots still occur.

Any thoughts??

I am having issues with my DHCP server having BAD_ADDRESS entries for a large number of addresses.  The Unique ID ends to be the reverse of the IP address in hex form. I have Conflict detection attempts set to 2.  It is only happening on the Scope attached to the secured wireless.  It seems to be about one bad address per minute or so. I've looked at the event logs on that server that I can find and there aren't any that match the time for the Lease.  Any troubleshooting tips?

XPS Document writer was removed from the 'Devices and Printers'

While troubleshooting the Feature was also disabled using: Dism /online /Disable-Feature /FeatureName:Printing-XPSServices-Features

I am now unable to 'Enable' the feature. "DISM failed. No operation was performed." (log is attached.)

Step 1. I'd like to get the Feature enabled.
Step 2. I'd like to get the XPS Document writer back to the 'Devices and Printers'

I have scoured about 20 blogs already; everything on this site, Quickbook links, scf scans, Sharing other XPS printers, deleting drivers, copying drivers, windows updates, add/remove Office365, DISM scans.
I am running VMware ESXi 6.5u1 hosted by OVH.

This morning i receioved an email indicating my server had stopped responding and a hard reboot was completed. Non of my websites had come online so I logged into the ESXi console. I noted that the hosts had not restarted.

I restarted the hosts and also enabled Autostart. Both of the guests restarted and were responding. However a couple of minutes later the ESXi server and guests again stopped responding.

I have again restarted the server and now it does not  boot to ESXi console at all. It does not respond to pings and apparently is not working.

I presume that it is the guests starting that is causing the server to stop responding.

I can boot the server into the OVH recovery image and access the server using telnet. However the recovery web console is not available.

Can someone assist in troubleshooting this. The first thing that I think should be done is to disable the autostart on the guests. Can this be done through editing a file from recovery?

So I am trying to troubleshoot replication issues in this domain with two domain controllers DC1(PDC), DC2(BDC). About a year ago the PDC stopped working and they were having issues with users logging, changing passwords and stuff so they promoted DC2(BDC). Upon inspecting today I found that the replication issues were caused due to netlogon service not running and every time a manual replication was tired "The target principal name is incorrect" as an error was thrown.

So after some troubleshooting the netlogon service is running now without any issues but now I am get the following error when I try manual replication.

The following error occurred during the attempt to syncronize naming context CN=Configuration,DC=Domain,DC=Local from Domain Controller AD to Domain Controller AD2; The directory service cannot replicate with this server because the time since the last replication with this server has exceeded the tombstone lifetime. This operation will not continue.

Also when I run the "netdom query fsmo" command both server claim to be owner of all roles except for DC2 not claiming Domain Naming Master Role.

netdom query fsmo on DC2
Schema master               DC2.company.local
Domain naming master        DC1.company.local
PDC                         DC2.company.local
RID pool manager            DC2.company.local
Infrastructure master       DC2.company.local
The command completed successfully.

Outlook not updating address book. If I try download the offline address book in Outlook, it gets stuck on connecting to Microsoft Exchange.

2 x Domain Controllers - Replicating to each other
1 x Exchange Server 2013 Standard CU21

Troubleshooting steps performed so far.

1.) Checked OAB Virtual Directories, both internal and external directories are pointing to the correct URL's but the OAB database hasn't updated for a few months now
2.) Run Get-OfflineAddressBook, shows the OAB as "DGE-Default <Ex2012>" and that it is a Version 4
3.) When I run the checks on the Arbitration mailbox, the Arbitration / System Mailbox cant be found.
4.) If I check in Active Directory all the System Mailboxes are missing.

I then moved on to troubleshooting the Arbitration mailbox and see if i could re-add them using the Exchange  setup.exe /PrepareAD as per a Microsoft Technet article.
This passes the prerequisites but fails when looking for the Default Email Address Policy

The operation couldn't be performed because object 'Default Policy' couldn't be found on 'serverXXXX.local'

Attached a copy of the Exchange Setup logs.

When running Get-EmailAddressPolicy I can see the 3 policies that are set up on the server but not the Default Policy.
If I run Get-EmailAddressPolicy -IncludeMailboxSettingOnlyPolicy then I can see the Default Policy as it has no email address properties attached to it.

I can't seem to find a way to add email address …
