The Ideal Solution for Multi-Display Applications
The Ideal Solution for Multi-Display Applications

Check out ATEN’s VS1912 12-Port DP Video Wall Media Player at InfoComm 2017. Kerri describes how easy it is to design creative video walls in asymmetric layouts and schedule detailed playlists ahead of time with its advanced scheduling feature.

I use the standard code using system.net.mail utilizing the smtp object. The Send method does not bomb, however the email did not reach the Inbox. Is there a way to check that the email was actually sent (I know it did not capture error). Where can I search for the email:
1- Check with the Internet provider?
2- Check my Junk mail (although I am sending it from me to me for test
3- Firewall????
4- any testing technique?

Actually it was working and I did not change the code or the settings (smtp server / port / Usedefaultauthentication / EnableSSl / Network credentials) what could have happened, and how to trace or analyze this?

Please help

Hi everyone

The company I am working for installs its images/OS via a network in UEFI.

How does the computer know on which server the image is stored?
Does the computer send out special packages via TCP/IP to retrieve the location of the images?
What protocol does it use?

I would also be grateful for a link to a site which explains the procedure.

Thanks

In chrome, authentication is successful. However, i am not able to access the folders.

I am running sql server 2008 R2. Everything seems to be running just fine.  The server is running on Scale hyperconverged servers.
When I try to run the report from my own desktop using studio management, or even when I RDP into the server, it does not work.
The report is called  "all blocking transactions".
Here is the error message.
sql error
When I log into the server directly via the console, the report works fine.   All other reports work just fine from my own desktop or even via RDP, it's just the one called "all blocking transactions" that does not work.

Any idea's if this is a sql issue or some kind of network problem, but I doubt it's a network issue, as all other reports are running just fine.

I have a client who wants us to set up a control that will prevent one of their computers from being able to be used if removed from the building. My thought is that the simplest way to accomplish this would be to prevent login if it is unable to contact the DC. However, I'm unsure if this is possible or how it would be accomplished.

My 10yr old Netgear WNR3500 seems too old and only giving up to 10Mb with our new equipment.  
Its RangeMax wireless-N Gigabit router.  Been good for us but.. for the last few years with newest devices seems compatibility issues there.

Should we stay with Netgear and get the latest model or some other good options around there?
Thanks.

one of our network guys changed the ISCSI software adapter on a host to the iscsi path of a san. how can it be changed back to the orginal.  It was origininaly something like iqn.1998-01.com.vmware:esx-79cf2f59  now its iqn.2011-06.com.sansdigital:sansdigital-000c28521:target2

I have disabled it and rebooted the host and attempted to add a new ISCSI software adapter but then it just re-adds the SANS digital. Since he has done this, now LUN's are presented.

Hi

We have SFB 2015 installed in our network. Due to some issue we have to remove the servers from network after deleting all instances of SFB and SQL from network. Now when we have reinstalled new servers and tried to publish a topology its shows an error where it is still pointing to old Server.

OLD SERVER FQDN: dclyncsql.gsi.gov.in
NEW Server: dccluster.gsi.gov.in

Please help me in how to remove instance of the old server and how to find out why it is still pointing to that database when all servers and SQL instances has been removed.

Thanks

I have a customer whose network is comprised of peer to peer computers. They aren't sharing anything locally. Their productivity is performed in the cloud. Recently an employee decided to upgrade the O/S on the computers without asking management. I know group policy on a domain would/could have stopped this but they are peer to peer. Is there any way to prevent unwanted action other than creating a policy for each pc? other than installing a server and creating a domain?

Hi,

Earlier this week we switched ISP's and started to use a new physical router with a different IP address on our lan.

At the same time we updated the default route on the Extreme switch so that it used the IP address of this new router as its gateway (therefore internet traffic goes out via this new router) .   The default route on the extreme switch is configured to use the "VR-Default" VR.

Everything has gone well with our production network, but we also have WiFi connections on a number of different  IP ranges (away from our production network).  We are unable to get an internet connection to clients on these WiFi networks.

These WiFi networks are also configured to use a different gateway (with an Ip in the range of the network) which ultimately returns them back to the the Extreme switch.  These WiFi networks/routes are also configured to use the "VR-Default" VR.

I would like to understand how I can examine the details/configuration of the 'VR-Default' VR to understand what IP address it is using to route out to the internet on.

I have a QNAP Turbo NAS TS-459, Firmware version 3.8.3 Build 20130426. Up to now it has been part of a Windows 2003 domain. However the domain controller has gone west and in Administration/Network Services/Microsoft Networking I'm trying to set it to a standalone server. The option is currently greyed out. I thought that if I disabled "file service for Microsoft networking" I could start over but every time I take the check mark out and hit "APPLY" the check mark reappears. Can anyone help?

I was experiencing significant interference and resulting wifi issues connecting a Lenovo Yoga 910 (which has limited USB ports) to my wifi network at 2.4 mhz.  I was using an USB 7 port hub which was adding to the problem.  I switched renamed the default network SSIDs which were the same at 2.4 and 5, then connected via the 5 mhz band and everything starting working very well with one exception.  My HP 8610 officejet printer operates solely at 2.4 mhz and I cannot figure out how to print (transmit the signals) from my laptop operating at 5 mhz to the printer wirelessly.

Can this be done and how?

Thank you for your assistance.

I posted something about this the other day and the responses told me that I need to use GPO instead of a batch file. I tried going the GPO route to create offline files and synchronize the User profile folder but it never worked. No matter who I added to security settings, or forced gpupdate, etc. It refused to synchronize.

So in the interim of getting that fixed, I need something ASAP that will do the same job but as a batch file. Here is what I created:

@echo off
cls
REM This script only backs up the folders under the user profile
REM i.e. C:\User\username\*.* It does not back up anything else.
echo This batch process will backup the User profile folders for "%USERNAME%", is this username correct? (y/n)
set RINPUT=
set /P RINPUT=Type input: %=%
If /I "%RINPUT%"=="y" goto yes
If /I "%RINPUT%"=="n" goto end
:yes
net use \\destinationserver\Users domainadminpassword /USER:DOMAIN\Administrator
pause
md \\destinationserver\Users\%USERNAME%
pause
icacls \\destinationserver\Users\%USERNAME%\ /grant DOMAIN\%USERNAME%:F
pause
robocopy "%USERPROFILE%\Desktop" \\destinationserver\Users\%USERNAME%\Desktop /MIR /SEC
pause
robocopy "%USERPROFILE%\Documents" \\destinationserver\Users\%USERNAME%\Documents /MIR /SEC
pause
robocopy "%USERPROFILE%\Downloads" \\destinationserver\Users\%USERNAME%\Downloads /MIR /SEC
pause

I have a Lenovo Yoga 910, which has one 2.0 USB port and two USB 3 ports.  I purchased a Wavelink powered USB hub for additional ports to support an external monitor and a USB keyboard.  I also have a bluetooth mouse in operation with this setup.  I am experiencing significant wifi issues with all the devices in use.  The problem seems to be interference at the 2.4 mhz band??  The performance issues go away when I disconnect from all external devices except the bluetooth connected mouse.  

Also, when I connect a wide screen LG monitor using an HDMI conversion to USB 2.0 into the USB 2.0 port, the monitor and laptop displays work, but the laptop display initially fades to almost totally black and then pops up with the screen, when I access the internet.

The more I read online, the  more confused I get about solutions.  My network adapter is - Qualcomm Atheros QCA61x4A.  When I perform the netsh command it looks like it should support the 5 mhz band.  I also signed into my router which looks like it supports the dual bands.  

My question is whether I am on the right track or not and how do I change my network adapter to receive the 5 mhz signal.  I cant see that as an option in the properties.

Thank you for any assistance you can provide.
