I have a single user that cannot get their mobile device to connect to exchange active sync. We have a policy that quarantines all new devices so I can approve them as soon as the user lets me know they have connected the device.

Troubleshooting I have performed:
1. Attempted using another device. No Quarantine notification and unable to sync.
2. Disabled the mailbox and purged from the DB.
3. Re-created the users email account and still unable to sync with devices or get quarantine.
4. Wiped the device and attempted to reconnect still unable to get quarantine.
5. Deleted the account in AD and Exchange.
6. Re-created the account and unable to connect.
7. Created a test account and am able to connect.

Im really at a loss as to why this account will not allow devices to connect to active sync. Its a single account of 2100.

Anyone explain how Exchange 2010\2013\2016 work with IIS?

Are there any good websites that go into where the dependency lies?

Troubleshooting an issue with websense , (forcepoint version 8.4) on client windows 10 machine where access to the Exchange Management Console doesn't initialize when triton AP-endpoint is enabled, (when disabled it works as expected)

Is there a way to isolate the cause of this, thought it might be port or IIS related but not 100% sure, (3rd party have a call open with forcepoint but no updates from them so far)

My organization has been having an issue for a few months now where a user will try to unlock their Windows 10 computer but no field populates to enter their password.  Sometimes the username will appear, other times nothing will appear.  On the lock screen you can see the date and time, but once you hit enter, it goes blank (you can still see the lock screen wallpaper).  A simple restart will fix this, however at the rate this is happening that is only a work around, and if the user has an unsaved document that presents a problem.  The troubleshooting steps I’ve tried based on my own research have been to disable Fast Start under Power settings and to make a registry edit which disables the lock screen.  Disabling Fast Start had no effect and disabling the lock screen seems to at best lessened the frequency of the issue occurring to once every two or three weeks.

We have ESXi 6.0 hosts with vCenter appliance version 6.7. Needed to move vCenter and ESXi hosts to a new IP subnet. Changed IP address of vCenter a few weeks ago without a problem.

Yesterday, after putting an ESXi host in Maintenance mode, I changed its management IP and after hours of troubleshooting, the ESXi started responding on new IP, with old name. (There is redundancy in links.) However we cannot reconnect this ESXi host back to vCenter now.

This host and vCenter are on the same subnet. (They can ping each other.)  I have restarted management service of host a few times. Have also rebooted host and vCenter. Still get the same error: "Cannot contact the <> host (10.0.xx.xx). The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding."
Please advise. Thanks.

Hi Experts,

Paty Mason was granted full access to Resource- Benefits, with the ability to send emails as the resource account

She is the co-owner and needs to be on the account's profile to create daily rules, however, she has been unable to send emails as the account.

Troubleshooting done so far:
•      Repairing her profile,
•      Removed her access and grant her access again
•      Removed her Outlook profile and re-added all resource account profiles.
•      Was then about to add Mailbox account and view the emails but still cannot send emails.
•      Search Error 0x80070005-0x0004dc-0x000524 on forums.
•      https://www.admin-enclave.com/en/articles/exchange/292-resolved-you-do-not-have-the-permission-to-send-the-message-on-behalf-of-the-specified-user.html\
o      See possible 10 solutions.

The user is still unable to send emails as the resource and is unable to use the profile, as she is getting the server error on the attachment. The resource is working as it should for all other users.  Other resource accounts to which Patty has access are also working as they should.

User got the NDR whenever she tries to send the email. Refer to screenshots

Can someone please provide instructions step by step to resolve this issue including screenshots?

Hello,

I am troubleshooting some Exchange Server 2013 problems related to ActiveSync, and I need to be able to use the test-ActiveSyncConnectivity cmdlet.  I've followed the steps as outlined in the Microsoft Doc here.  However, I receive an error message during the initial New-TestCasConnectivityUser.ps1 script execution (looks like setting attributes to the test mailbox), and I'm unable to execute the test-ActiveSyncConnectivity cmdlet after the script completes.

Hello and Good Morning Everyone,

            Following some extensive troubleshooting, I am now able to fully access my friend's Windows 8 desktop.    At this point, I am wondering if there is a way I can configure Windows 8 so it will by pass the username and password requirement and go straight into the desktop environment.  At the moment, there is a screen with an email address, personally set up, along with a box requiring a password.  Once the password is entered, the HP Pavilion laptop takes me straight to the Windows 8 desktop environment.  Basically, I want to eliminate the login requirement and go straight to the desktop.  

             Any help regarding this question will be greatly appreciated.

            Thank you

             George

Hello and Good Afternoon Everyone,

            For troubleshooting purposes, I need to know how to access the BIOS settings of an HP Pavilion laptop running Windows 8.  Unfortunately, I can not locate the model number of this laptop anywhere on it.  Hopefully, the steps for accessing the BIOS for the HP Pavilion laptop are universal.

            Thank you

Good Morning Experts,

Mary Doe has publishing editor permissions to John Doe’s calendar.  She recently cancelled an appointment she created on his behalf, however, we have been unsuccessful in deleting it from her calendar.

The meeting attendees are also receiving several cancellation notices.  These seem to be sent sporadically, as the most recent was sent out yesterday, and Mary has not been sending them out.  

Last week, I was remoted into Mary’s computer to try and resolve the issues with this appointment.

I did a repair on her Outlook profile, removed her Outlook profile, tried to delete the appointment via webmail, and was not successful.

I also RDP into John’s computer this morning and did a repair on his profile, removed his profile, and also checked on Mary’s permissions to his calendar.

Everything seemed to be in order on his end.  Could your please look into this further, as I have run out of troubleshooting options?

Please, advise how to stop getting this cancellation meeting notices on user's mailboxes and explain what would happen if there are several scenarios

Provide step by step instructions with screenshots

Experts,

I have a DFS server which I am decommissioning and have moved all the files from it to a new 2016 server which will be replacing it. I have installed the necessary DFS components and have created an additional folder target in my DFS Manager to the new location.

After I robocopied the files making sure to retain the permissions, I Enabled the new folder target and disabled the original target.

Since that time. I left the referrals to update over a weekend and then tested my dfs structure using dfsdiag. dfsdiag was not reporting any issues with my infrastructure so I thought I was good.

Most of my computers have updated and pulled the DFS Folder without issue, However there are some problem children that are not seeing the new location and instead are defaulting to the old location. This is the same behavior seen when accessing the location though either a mapped drive or direct unc to the DFS folder location.

Please assist me In troubleshooting this issue if you are an expert in DFS

Windows update not working on server 2012 r2 standard.

Tried the general Microsoft Site for the Update Readiness Tool

Tried the following Microsoft Site for general update failure.

Finally looked through the Windows Update Troubleshooting site. The manual approach requires registry settings so take great care.

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.

Hey everyone -- I originally came to Experts' Exchange to address a bedeviling c0000218 blue-screen error, but the discussion has kind of splintered a bit, so I'm going to open a new question.

In the original question, the consensus seems to be that the Ultimate Boot CD for Windows (UBCD4Win) is the best method of repairing the registry error which is preventing me from booting my computer. The original source for the program is now defunct, but it still exists around the Internet largely as freeware. Though I'm convinced that the program may end up doing the job I need, it's been a bedeviling journey just to create the necessary file(s) to carry out the process. Several attempts to create or use the program have not ended successfully so far, and I'm at wits end to understand why. I will detail one of the more recent attempts below; to follow some of the previous attempts, start with this comment on my other question; you could work upward or downward from there, I guess.

After a recent failed attempt to build an .iso file from the program, I took a closer look at the log and found a pair of errors which caused the build to fail. As suggested by another forum user who commented on my update to the original topic, it turns out that the Windows XP operating system I'd been using to facilitate the build was corrupted by a couple of missing registry files, as the image below will show.

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.

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?

Thanks a ton,":0)  Asta

Hi Experts,

since yesterday we have some strange issues with WIN10 machines.
When the user logs in, the screen is black and you cannot click anything.
We have checked the monitors and cables, all ok.
Do you have any infos about this ?

When I check the services from this machine, I can see a lot of services are in starting modus.
See the screenshot.

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 3.1.2.11 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 …
