Programmer needs help setting up network after virus attack

I paid for and got some DELL support to reinstall a "fresh" copy of my Windows 2008 R2 OS after a virus essentially wiped out my network.  So, now I have to re-setup my network so that everything on the network connects and I can connect to the internet thru my SonicWALL device.  Problem for me is that I haven't had to do anything like this since 2013, when I first set up my server and I'm lost.  I can't get the basic network set up and this is, obviously, delaying my restoration of my Remote Desktop Setup (which I've worked on more recently, so I think if I can get the basic network up and running (and I mean "just the basics"), then I'll be able to move on and set up everything else I need to provide remote access to my application.  Being a programmer first and technician last, I just don't have the experience setting up networks, OS setup, etc. that other people in this forum have.  So the question at this point is how do I set up the server OS to connect to the rest of my network and the internet?

Does the DNS setting have forwarders active (using the IP address provided to you by theISP? or 8.8.8.8 & 9.9.9.9 for the time being?)

(I don't do GIG's, i have a deep distrust. w.r.t. Paypal, they cost me too much money in the past amongst which i was charged for getting no service at all
a payment done, wich was revoked by Paypal except for two times the fee of transfer, and another payment which was declined on "US political grounds"  again Paypal didn't mind  getting their % of the payment (1 time this time)).

you will need to assign a network address/netmask to your system as well have a default gateway pointing to your SonicWall.

Maybe to get started you can set it to DHCP until enough is available on your server to start servicing for your network.
Then assign the address of the old server to thisone.

You should be able to set the network address from network centre or something like that from the network image on the bottom right of the screen. There select you connection , and from there properties and TCP/IP settings.

This expert suggested creating a Gigs project.
1) Is this a Windows Active Directory domain server, or is this a stand-alone server?  Did you configure AD when you set the server back up?

2) Are the workstations in your network configured for DHCP (if nothing is connecting now, and you dodn't change the firewall, the answer is probably "yes").

In an AD environment, the AD server(s) usually provide authentication, DHCP, and DNS services to all of the workstations in the network.  The AD servers are typically statically addressed.  Something like this (assumes 255.255.255.0 internal netmask).  Specific addresses just for illustration, you'll need to provide proper addresses for your network.

192.168.99.1 - Sonicwall inside address (default gateway for your network)
192.168.99.2 - AD Server, running DHCP Server and DNS Server.
DHCP server will hand out IP addresses in 192.168.99.x network, 192.168.99.2 as DNS server, and 192.168.1.1 as default gateway.
DNS Server be configured to handle local requires, and will forward other requests to a public DNS server provided by your ISP or by a third party like Google.
Workstations will be configured to obtain all settings from DHCP.

If this isn't an AD network, then the Sonicwall might be providing DHCP, or you might just ahve statically configured workstations.  Look and see if DHCP is configured, but if Sonicwall was providing DHCP or you were using static IPs, I wouldn't expect a service interruption.

Last thought: instead of trying to DIY, why not get a little professional help?  Good network guy can probably iron this out for you in less than an hour.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

This IS an Active Directory domain server.  In fact, I've invested heavily (at my customer's expense) in a number of Active Directory tools for bulk adds, self-service password changing, etc. and, yes, one of the first things I did was to install the AD role on the server.  I have a default gateway (the address of my SonicWALL) using a 192.168.x.x address.  I also have static IP addresses for all of my computers and NAS device, but since they're currently not working, I'm using DHCP from my cable modem to at least connect to the internet to be able to correspond with the EE folks.  I'm thinking that one of the issues that I'm having is with DNS.  I set up the server to be a DNS Server as well, but I don't really think that part of it is set up correctly!?  As for your last suggestion, I'm located in a seasonal area of southern New Jersey where business is all but non-existent.  So, that's not really an option for me.  I going to go back and set my IP addresses back to my hard-coded static IPs that match my default gateway and see what happens!?  I'm not familiar with the GIGS solution, so if you explain that to me I would appreciate that as well.

Gigs: you post a project and a budget on EE.  You get bids from Experts to help you one-on-one.  It is project oriented.  Also the Live product offering where you can buy help in 15 minute increments.

Start the troubleshooting process by getting on one of the workstations and making a note of the network settings for the primary connection you use.  On Win 10: Control Panel-Network and Sharing Center - Change Adapter Settings - Right click active connection and select Properties.  Select IPV4 or IPV6 (whichever you use, probably IPV4), and select Properties.

What are the IP and DNS settings?
Flip to Alternate Configuration and provide any info found there.

While you are there, open a Command Prompt and enter IPCONFIG /ALL - note/cut and paste all of the settings for the adapter you were working with in the previous step.  Post that info too.

Nothing in here is secret or security sensitive as long as it is just private addresses (192.168.x.x from your example is a private range).

Use the PING command to ping:

Your server by IP address and by IP name
Your Sonicwall's inside gateway address
A google name server by name (google-public-dns-a.google.com) and by IP address (8.8.8.8).

Post results of each ping (succeeded/failed).

The GIG solution is basically offering a paid job on here for a qualified individual to fix this for you remotely.
They will work with you over the phone to get enough remote connectivity to get in, and then with your specifications get everything going for you... It is a bit of work and would not be free...

The other option is to stumble through it yourself and ask a question for every place you get stuck...

One gets you up in hours, the other could take days or weeks...

I really recommend you get a good regular backup also so you don't have this problem again in the future... You could probably start with some usb backup drives, and work up as money allows...

I was able to get the server to connect, thru the switch (that sits behind the SonicWALL) and I have internet access with the server.  So I'm making some progress.  I still am not able to access the internet on this workstation (my primary) when it's connected to the switch.  I only have internet access when connected directly to the cable modem.  Obviously, I need to be able to get this workstation (as well as my NAS device) connected to my local network and still be able to reach the internet.  That's where I'm at currently.  I have 2 technicians from my client corporation coming here tomorrow, but would like to get as much done as possible before they get here (for obvious reasons).

The handling you need to for your workstation is the same as for your  server you need to change the network properties of the adapter.
and try a ipconfig /renew  if connected in the right way... (did you also start from scratch on this system?)

Sorry I couldn't respond sooner, but I had to deal with some "politics" with representatives of my corporate client all day.  Since your previous post, Gary, I've actually come a long way.  I now have the entire network up and running, with everything running behind my SonicWALL device and have internet access  from all of my computers.  I have a "bare metal" backup on a Buffalo Terastation NAS which I'm trying to restore my server from (to avoid reinstalling all my applications and settings) and this it the one device that I'm still having problems with.  While it can be seen by both my workstations and my server, I can't connect to it for some reason.  If I didn't have to deal with these other people, I would have spent most of the day with Buffalo Support to figure out some way to get this device back up and running (as it always had in the past) on my network.  Since I backup daily, the last backup I have is just prior to my virus attack, so, if I can restore that backup, that would be my quickest way to get this thing recovered and back in action.  Otherwise, I have to reinstall all my applications, install SSL certificates and re-setup my entire Remote Desktop environment.

Glad you are almost there! I'm sure Buffalo can help you figure out what is wrong... probably a subtle settings difference...

I'm getting close to where I was before the attack which is the good news.  I'm taking everything step by step, so the server's up and running and connecting to both my network and the internet, going thru the SonicWALL device.  I've reinstalled my SQL Server and restored all the databases and I can run the software application from the server (have an issue when running from my workstation, but that can wait for later since my clients run directly on my server anyhow).  I've re-keyed and downloaded new versions of my SSL Certificates required for my clients to be able to connect remotely to my system using Remote Desktop Services (one SSL for the Remote Gateway and one for the Host Session server).  Setting up the Remote Desktop Services has always been a nightmare for me and, again, despite the number of times I've been thru this process, it's biting me in the "butt" again.  I've got tons of screen shots that I took the last couple of times I went thru this process and, together with what I remember about the process, I really thought I had everything set up just the way it was before.  But, of course, something's off and it's not working.  Here's the error message I'm receiving and I'm hoping that someone who has worked with RDS and has set up RemoteApps for remote users to access will have some insight into this:
RemoteApp-not-connected.jpgAs always, I'm going to keep working on this, but if anyone has any suggestions, please pass them on....

Basically, I worked through this situation myself, but I always appreciate other ideas and points of view.  My best solution (since it's not an option) was for noci's advice regarding getting involved with GIGs....Thanks for that tip!  I've started another question (essentially a continuation of this question since I still don't have my clients back in business) focusing more on my current situation.  Thanks all!

I thought that I had closed this question out already.  I appreciate everyone's contributions and noci got the Best Solution for his tip regarding GIGs.  My network is up and running and my focus now is on the Remote Desktop Services issues that I'm having, so I started another question line to "zero in" on that one specific area.  Thanks to all!

if forwarding to 8.8.8.8 & 9.9.9.9 was the solution the 2nd part should maybe be redacted out or placed in a different comment.

If it was about GIG's ..., you will not find me there... i have had a few bad experiences with Paypal  and won't touch that service again.
Gig's might be great the rewarding system for it is a no-go area for me.
Then better accept your own answer with the comment...  and set point to who you want as a contributing part to your answer.
