Hi, I'm using the Quarantine feature from Watchguard and this creates a Quarantine website users can log onto. But the problem is that it's an intranet server and as such doesn't have an 'official' SSL certificate. I tried to create a self-signed one etc but I keep on failing ... could someone please give me step-by-step instructions on how to create a self-signed certificate and attach it to that website so that the browsers won't throw their security warnings anymore? Thanks!

We have a Windows domain with a 2003 Server domain controller with Windows 10 Enterprise computers.  I plan on taking a computer off the domain and connecting as a test to Azure Active Directory.  My goal is to retire the local domain server and have all our computers completely on Azure Active Directory.  The one problem is there is a QuickBooks file that is shared on the local domain controller for the accounting department.   If I am connected to the Azure directory, can I still connect to the domain controller to share this one resource using the Windows 10 machine?

We've got an issue, an IIS web application can't access a file on a shared drive.
The app pool credentials are the same as the desktop user credentials we are logged in to the server's console. The account is a domain user account and also an administrator on this web server (it's an intranet server). The anonymous authentication is set to "application pool credentials".
From the windows UI the shared path is fully accessible both via an UNC path and mapped drive, but running from the web app we are getting an "LOGON FAILURE"  in the Process Monitor log.
I tried to create a virtual directory pointing to that shared drive, but IIS can't access the web.config neither, displaying a 500.19 server error with a error code 0x8007052E

I don't understand, what could prevent a domain account to access a shared folder on another machine in the same domain just because it is being running from an IIS process?

My Windows 10 computer can't access shared folders on older versions of Windows.

For example, I can connect without problem to a file share on Windows Server 2008 R2, but I can't connect to a file share on an old server that is running Windows Server 2003.

I've accidentally deleted my domain user account and I want to recover it.  I read there's a way to do it using LDP, which I will try.  My question I have it I first recreated my account using the same username, so do I need to delete this new account, before bringing back the old account?  Or will it rename it and "move it out of the way", so to speak?  Has anyone used LDP to restore a domain account before?  any pitfalls?

Thanks,
Damian

I have a Windows 2019 file server (not AD joined) in a DMZ with SMB (IP port 445) opened for file share access from an internal Active Directory based network. I'm looking for a method to authenticate to the file share and to manage access to the share for users.

How can I determine what device is on our network?   I can ping the IP but I do not know what the IP is attached to.   I tried entering it in the browser but it does not find it.

what kind of activities on a windows server would actually require local administrator privileges, or as a server engineer yourselves, what day to day tasks do you perform on windows servers that do require you to be a member of the local admins group. We have got to go through the local admins groups on a number of critical servers and the numbers seem on the high side, but I want to be equipped with some examples of when you do need local admin rights to query if these users would ever need to perform such a task as part of their duties? If I could get something like the most common 5 admin type duties that are performed on windows servers that do require local admin rights that would be a start I suppose. I suspect in many cases those with administrator group privileges on some of the servers have no real requirement to have it. In case its of interest the vast majority of these servers run Windows server 2012.

Windows Server (2019) network connection loses identification every few days.  The Network location/lists services need to be restarted to get the local domain identified again.  This is happening on the DC/DNS server as well as one of the DB servers.  Searching I'm not finding anything to identify what is likely a config issue.  Any tips?

We installed 10 new Win 10 computers.  5 at each of our locations.  At one of the location I cannot ping any of them.  They are working fine just cannot access them remotely.  

I have not had this happen before.

What could it be?

Windows 10 Pro: a Lenovo PC drops the Ethernet network connection at almost exactly two-minute intervals for about 12 seconds (three or four pings).  I'm working remotely on this PC so I'm limited in what I can do without going on-site.  Watching Device Manager it seems like the Intel 82579LM adapter drops off the list of installed devices and is re-added during these two-minute intervals  If I leave the list of network adapters collapsed, Device Manager shows that list re-expanded after RDP reconnect.

Nothing shows up in event logs in terms of corresponding events happening every two minutes.  Installing a new driver update from Lenovo didn't help.  Already disabled power management on the network adapter.  Disabled IPv6.  Tried both static and DHCP addressing.  Verified that there are no scheduled tasks running at two-minute intervals.  Tried Network Troubshooter during the 12-second downtime window and it reports there was "no gateway" and that it reset the adapter.  However running ipconfig during that 12-second window shows there is.  (I wrote a batch file to log ping failures and run ipconfig since I'm working remotely).  No difference when pinging a local PC on the same subnet or a a public IP address.  All WIndows updates are up-to-date.  System also has a WiFi adapter which I disabled (no difference enabled or disabled.  Also note there no available wifi hotspots on this network).   Would appreciate any insight into this frustrating problem, especially as it …

I am the sys admin in a large organization that practices 'separation of duties'.  At my division I have admin rights to do everything, EXCEPT logon to the domain controllers.  I am trying to track logon events on local member servers, but I can't seem to get the audit logon events listed in event viewer.  I have server GPOs to enable success/failure of 'audit logon events'.

I thought 'audit logon events' are shown on the local server and 'audit account logon events' are shown on the domain controller?

How do I audit local logon events on the member servers?

are there any specific event logs on windows (windows 7) that indicate the exact time a machine was powered on and off. I know from analysis and testing of security.evtx its pretty close if you pick the first and last event of the day to the time a machine has been on/off but I did wonder if there was an exact event in one of the windows and/or applications and services logs which would specifically relate to power on/off for a laptop device.

Introduction to R

Introduction to R

R is considered the predominant language for data scientist and statisticians. Learn how to use R for your own data science projects.

I have 2 PCs that are both connected to the same WiFi network.  Both PCs are on the same work network, both have the same workgroup name and I have toggled network sharing off and on - on both of the devices.

Neither can ping the other.  However, where it gets strange here... If I run simultaneous cmd pings of each other, #1 PC starts successfully pinging the other, but stops if I stop the ping attempts from the other PC to it.  #2 PC pings never resolve.

Both devices are Dell Optiplex 3030AIO and on Windows 7 Pro, Service Pack 1

Setup: Windows 2019 Server with 2 network cards: 1 and 2.
Assigned static IP 192.168.0.111 to NIC 1 netmask 255.255.255.0, DG 192.168.0.1, no problem.
When assigning static IP 192.168.0.112, netmask  255.255.255.0 DG 192.168.0.1 it throws me a warning:
"Microsoft TCP/IP Warning - Multiple default gateways are intended to provide redundancy to a single network (such as an intranet or the internet). They will not function properly when the gateways are on two separate, disjoint networks (such as one on your intranet and one on the internet). Do you want to save this configuration?"
I said yes, but then I lost connection to the internet. Ran the troubleshooter and that reset NIC 2 to DHCP (dynamic).
I am probably missing something here.

This is in reference to my previous ticket, that has not been really resolved fully:
https://www.experts-exchange.com/questions/29151189/How-can-I-separate-the-IP-phone-system-from-computers-for-less-than-50-users.html
To double the number of hosts, I was suggested to just change the subnet mask from 255.255.255.0 to 255.255.254.0. That is supposed to bring up the number of hosts to 510.
Because I haven't done this before, I would need assistance with:
- how to do it (if it's possible at all in our case)
- what else it implies
And any other detailed info you could suggest.
Thanks in advance and feel free to ask questions.

Hello,

I have industrial machine needs to connect to an Access Point in order to download data through a software designed by the manufacturer, I am thinking instead of getting Physical Access Point "especially the machine is working in a sever application" to use Virtual Access point on the LAPTOP, tried ICS "Mobile Hotspot"  but this is not helpful because I need the machine to use 192.168.0.1 / 255.255.0.0

Is there any Free Virtual Access Point can be download works with Windows instead of using ICS  instead of physical AP? or is there a way in Windows 10 to change IP address and subnet Mask for the clients ?

Thank You
