What do you use when you need to run a cable through a wall or from the outside of a building to the inside of a building? I want to put in some kind of "grommet" just big enough to get one network cable (with ends) through. The walls will vary in thickness.

   My first thought was to put a short PVC pipe through the wall then find some kind of "flange" to put on both sides of the PVC pipe to hold it against the wall on either side. Surely there is something out there that is a "professional" way of getting a cable through a wall or from the outside of a building to the inside of a building. I just don't know what it is :)

I am using below extended monitor.

screen looks very bright to my eyes

i could not find any option to reduce brightness.
on right hand side bottom corner i see some buttons like 5 of them.
First one from last is to switch on and off
other four are very clear to me
i played around but no luck to reduce bright ness

Please advis
I have a server with multiple virtual servers on it, was wondering is adding a network card with more ports will help for performance, since I use gigabit switches so the most throughput on the network is a gigabit how will I gain with a card with 4 ports each a gigabit if the switch highest capacity of the switch is a gigabit plus the switch is handling not only the server?

Any recommendation for a nic card and if not much more expensive can do nic teaming.
dear Experts.
i am having an issue with HP 522SFP dual port 10gbe NIC under windows 2016
i tried everything to my knowledge to get it to work and every possible driver from HP or even from Qlogic (assuming its a Qlogic card) finally under windows 2016 i always get this error

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

can anyone please advice me?
i need to get this to work .
We have purchase the new Aruba 2530F and our HQ instruct us to create the SVI’s in the switch and perform the intervlan on this switch. I have some doubt regrading this configuration and hope that expert can advise me.
1.      For all the printer we should use which vlans
2.      From the switch I can see that have option for us to check primary and management in vlan interface, let said in this information provide by HQ should I enable “management” in  VLANS 4
3.      What is native VLANS
4.      We try to enable the management in VLANS 4 ,we lost access or web console but we still have connectivity ?
5.     we should connect all the configure all the management port in VLANS 4 ?

I have a Singamax cat 5e patch panel connected to a Cisco 24 port gigabit switch and my machines which have gigabit cards are only connecting at 100mbs?  Any ideas?
We had a 2016 server yesterday that could not connect to the Internet.  I found one of the NIC adapters did not have the Default Gateway setting.   After adding it the server was fine.

Now again today the same server has lost the Default Gateway.

What would cause this?
Hey all
Moving to a new office, was going to go with a TZ400 for a router/firewall/vpn solution.

Have two separate factory areas, both have metal covered walls. We are going to want to have Wi-Fi in each of these rooms for the factory workers handhelds etc.  Ceilings could be 24’ ft plus, I need solid reliable solution that just works for Wi-Fi.  It would require multiple points so therefore a controller to hand off from point to point as they make their way around the factory floor etc.  Hoping for simple/reliable – easy to administrate.  Thoughts/ideas?
Good Morning Experts,
I have a question about SAN units. I need to replace my current Equallogic PS6100 which has approximately 32TB of storage with 22TB currently used. We are a medical practice and our application vender which provides the application which uses this SAN normally drives my purchase decisions. This unit is over 5 years old and I am ready to replace it and the server that uses it. Currently the server using it boots from the SAN and is the sole user of the device. We won’t be booting from the SAN in the new setup and will have two servers attached to the new appliance. The servers that will use the SAN will be physical servers not VMs. The SAN will probably be setup so the SAN has dedicated storage (volume groups) for each of the two servers; one a production PACS (Picture Archive and Communications Server) and the other an EA server (Enterprise Archive). Because I need roughly 50TB per server to store what I have plus grow over the next 5 years I am looking at around 100TB of storage total.
I originally wanted to stay with the EqualLogic platform but my vendor is advising against that with the main reason being the platform will be phased out. I understand they will be discontinuing service on EqualLogic appliances sometime around 2024 which would carry me past my next 5 year cycle.
The vendor is recommending either Dell/EMC Unity the 300 series with around 100TB in the hybrid configuration. I don’t have a problem with the unit but price is a …

I have 4 locations that are utilizing gateway to gateway connections. 3 locations have the Cisco RV325 Wan VPN Routers and one has an ASA. Under the VPN Summary tab the 3 VPN connections were all connected at one time and recently the status went to waiting for connection. Nothing has changed that could have caused this that im aware of. I tried switching them all to aggressive mode and back but it still goes back to "Waiting to connect".

There are 4 sites, Office 1, Office 2, Office 3, and Office 4.

All of the offices are connected to each other except office 2. Office 2 is waiting connection to all of them.

I've compared the settings side by side and they are all the same.
Hi - I'm working with an older Sonicwall TZ 100, where the firmware was last updated in 2009 (Sonicwall Enhanced - May 21,2009) and they've been having some flaky internet issues, and I'm wondering, being that the firmware is so old, is it ok to update to the latest version from a version thats 9 years old? (the latest appears to be version - Oct 2017) Has anyone ever done this with firmware that old, and will I have any issues? Any help would be appreciated - thank you
We have total 7 scope configured in DHCP out of which 3 is showing blue exclamatory mark, when I click on display statistics for these 3 scopes all value is showing zero only. Event logs showing error messages like "DHCP client request from C42F909FAB66 was dropped since the applicable IP address ranges in scope/superscope VLAN40 are out of available IP addresses. This could be because of IP address ranges of a policy being out of available IP addresses." for all these 3 scopes only. However all these scopes are not more that 50% occupied.

DHCP lease is 10 hours for all scopes except scope for mobile user.

In DHCP properties DNS Tab
""Dynamically update DNS record only if requested by the DHCP clients"" is checked.
""Discard A and PTR records when lease is deleted"" is also checked.

Assign IP addresses dynamically to clients of: is DHCP

In DNS Scavenge stale resource records are set as No-refresh interval 3 days and Refresh interval 4 days for all the zones and scavenging Period is 1 Day.

I performed the reconciliation and restarted the DHCP services in both DC and is ADC. Also I checked by restarting our ADC as it was also showing the same thing but it also doesn't work however I have not cheeked  by restarting our DC yet.

Please suggest if anyone having the solution for this.
Hi - currently we have several Cisco 2960-24PC-S 10/100 POE switches, that we are going to be replacing with Cisco Catalyst 2960X-24PD-L POE switches, because of age and the need for the gigabit connection. My question is (my limited Cisco knowledge) that we have SFP Modules that we cant seem to figure out the model #. In the inventory on the switch it shows up next to the Description as "1000BaseSX SFP", and the serial number below it. Does anyone know if these are compatible with the 2960X switches?
I have few offices that I need to support, I always assist remotely the business users.
Was wondering if there is a KVM switch that connects to the internet, and then I can plug it to a computer via USB and VGA so I can control the machine remotely, even via the bios. Kinda like HO iLO.

Any recommendations ?
Does anyone have a good example for implementing QOS on a Nexus 9000 switch ?

Hi ,

we have subsidiary company with around 150 Users . it is linked to us (HO ) over IPVPN (1 MB)  and services getted from Us are :

1- CISCO IP telephone ( currently around 75 Users)
2- ERP ( about 50 USers)

1- Domain COntroller ( seprate totally from us ) + Antivirus server ( 1 physical box)
2-finance system
3-Backup Server
4-Sonicwall NSA2600
7-Router for IPVPN

the managment is thinking to host the setup for the subsidary company so my questions are:

1- how I can do the proper sizing for the link ? so i ensure the users are not feeling slowness
2-what equipment should i move from there and what i should not ? best desing fro myour experince
3- how the internet should be provided to thier users ? from us or locally ?
4- what are the adv and disadvanage for such plan? should we recommend this plan or let them continue as they are
5- risks?
6- what are the pre requisits needed in the HO Data Center for hosting those equipment
It seems that the documentation about IPsec/IKE setup on an SRX to Azure s2s VPN is conflicting.  There are 3 pain points:

1.  Can IPsec/IKE be used on a policy-based VPN for Azure? It seems that Azure is clear about "no" but the suggested Azure config includes IPsec & IKE config
2.  Which IKE version is best for SRX to Azure - v1 or v2, when using Policy Based or Route-Based VPN? (see attachment)
3.  If a trust sec zone (internal interf.) and an unstrust sec. zone (exter. interf.) already exists, how can I add interfaces that are in one of those zones already to a new "Internal & Internet Zone" for the Azure VPN Tunnel as documentation suggests?  I receive an SRX error about adding interfaces to multiple zones prohibited and if using PB VPN there is no st0.x to that config and/or I don't understand how to utilize or place the traditional interface under the st0.x iface.

I need a powershell line that looks for a local LAN adapter on a system that doesn't have one and the output is null? I've toyed with this and cannot find something that works.  I'm hoping that someone out there has this handy and would share,

Hello- I am in desperate need of help. I implemented a Cisco SG200 Smart Switch. There are only 24 gigabit ports, so I attached a 24 port unmanaged Cisco switch to it. However, most (not all) computer and VOIP phones are not able to obtain IP addresses from the UTM connected directly to the Smart Switch. The LAN adapter on the computers say "Unidentified network".

I have been researching this for 6 hours and I can't figure out why these devices are able to get an IP address.

Thank you.

Hi all, looking for some assistance with a SQL cluster issue, would appreciate any assistance available.
xxxSQL07 is the name of the SQL cluster (windows cluster name xxxSQLCLU02) made up of two nodes; xxxsql03 and xxxsql04.
All works, able to connect using SQL studio using Windows Authentication (tried multiple accounts, including the service account that all SQL runs on on this domain).
The problem has presented itself as we've recently created a reporting server (xxxrpt02). The local publication has been configured linking to the only database on xxxSQL07 and wizard completed with no errors. From SQL studio on xxxRPT02, when trying to add a local subscription I receive the error message, "The target principle name is incorrect. Cannot generate SSPI context. (Microsoft SQL Server)". I've tested the reporting server by connecting to a local subscription on another SQL cluster which works, I also tested the faulty domain cluster from the other working reporting server and received the same error.
This error occurs whenever I try to connect SQL studio to this SQL cluster. I've also tried connecting to the name of the windows cluster but that didn't work.
In an attempt to fix this issue I took the xxxSQLCLU02 offline from failover manager and performed a repair in an attempt to get this connecting in to Active Directory correctly.
The SQL cluster name is pinging and the IP is resolving when pinging -a.

I've done some digging around and am erring toward this issue being…
